Do you know what should be the height and weight of the child by months? Average normal for infant boys

Each child lives according to their individual program of growth and weight. However, there are statistics that give an idea of ​​what the average weight of children is like. Also, there are recommendations from doctors who offer optimal values ​​for height, weight, and their ratio.

We compared the data obtained by statistical means and the recommendations of doctors, it turned out that they practically coincide with a difference not exceeding 3%.

So, the data given in the table are the optimal values ​​\u200b\u200bof the height and weight of the child. Please note that the values ​​for boys and girls are slightly different.

How to use the table

How much should a child weigh? In the left column, look for a line with the text 1 year. On the right will be weight in kilograms (boy 10,300 / girl 9,500) and height (75.5 / 73.8) in centimeters.

Weight Estimation

The deviation of the child's weight within 6-7% of those indicated in the table is the absolute norm.

A greater weight deviation of up to 12-14% indicates a tendency to overweight or underweight.

A weight deviation of more than 12-14% indicates a slight overweight and underweight.

A weight deviation of more than 20-25% indicates overweight and underweight, perhaps in this case a small nutritional correction will be useful, carried out solely on the recommendation of a doctor.

For a more accurate weight estimate, use our or professional centile tables, or.

Growth estimate

The deviation of the growth of the child within 3% of those indicated in the table is the absolute norm.

With a growth deviation of more than 10%, it makes sense to consult a doctor.

For a more accurate estimate of growth, use ours.

Adequate assessment of the height and weight of the child

In general, the indicators of the norm for each child are different. Approximately 10% of children will have weight and height indicators outside the proposed assessment range and for them this will be the norm.

The weight of the child should be monitored first of all in order to detect any nutritional problems in time. For example, if a child abruptly stopped gaining weight or reduced it for no apparent reason, this is an indicator that some problems have arisen. Thus, for a complete analysis, it is necessary to know the history of the weight and height of a particular child.

Controlling weight and gain also helps to evaluate the optimal nutrition for the child: adjust to a certain diet, switch to a new mixture, normalize the consumption of porridge.

When assessing the weight of newborns, it must be remembered that during the first week of a child's life, a natural weight loss of 5-8% is normal.

Greetings, dear readers! All parents want their children to grow up healthy and develop normally. But how to determine that the baby is all right? Doctors recommend focusing on such important indicators as the weight and height of the child by months. Compliance with the standards proposed by WHO on the basis of research, doctors determine the degree of full-term infant and the quality of its further development.

World Health Organization, or WHO in the period 1997-2003. conducted a number of studies on the development of babies up to a year old, as well as a parallel analysis of the height and weight of children aged 1.5 to 6 years. The focus of the world organization was not only indicators, but also their ratio and monthly increases.

Why was such a global study necessary? The latest data on indicators of the physical development of children were recorded back in the 70s. 20th century. Since then, not only the rhythm and lifestyle of people have changed, but also the nature of the nutrition of infants.

If in the Soviet period the majority of babies were bottle-fed, then with the improvement of working conditions for lactating women and the opportunity to get paid leave after giving birth for 1.5 years, this has led to the fact that now more and more babies are breast-fed, which is otherwise reflected in the increase in body weight and length.

Data collection was carried out in different countries and ethnic groups: European countries, USA, India, Brazil, Oman, etc. The study showed that each nation has its own parameters, therefore, to derive the average length and weight, for example, for European and Indian children, it is forbidden.

What do the values ​​depend on?

Mothers who have at least once undergone a monthly examination with babies in a clinic know that a nurse not only measures and records indicators, but also pays attention to concomitant development factors:

• transferred viral and infectious diseases;
• the presence of dehydration;
• erupting teeth;
• the presence of appetite;
• upbringing conditions.

They have a temporary effect on physical development, which can be corrected in the future.

However, there are other factors that mommy or doctors cannot or can hardly influence:

• gender of the child;
• features of genetics (if dad and mom are tall, the baby will also be tall);
• the degree of full-term, as well as the initial indicators of height and weight at birth;
• nature of nutrition (natural or artificial);
• the presence of congenital diseases;
• mobility;
• ecological situation;
• the nature of the course of pregnancy (did the mother smoke, did she drink alcohol, etc.);
• the amount of somatotropic hormone produced, which is responsible for the growth of tubular bones (since most of the hormone is released at night, sleep disturbances in a child can cause growth retardation).

Good care, regular breastfeeding, adequate sleep, physical activity and outdoor walks accelerate the growth of children. In turn, insufficient care, poor environmental conditions do not have the best effect on physical development.

To check if your baby is developing normally, it is not necessary to rush to the clinic. Parents can take measurements on their own, based on generally accepted developmental standards and calculation formulas.

Child growth by months

Children's growth rates depend primarily on the sex of the child, therefore, for girls and boys, WHO has created separate tables with averaged indicators. Depending on the age of the baby, the ratio of body length and weight, as well as the increase, will also differ.

First year

The table shows approximate indicators of the growth of babies at birth and up to a year, you can also track how many centimeters the child will grow within a month.

For children up to a year, a special change in indicators is characteristic, and each month of life during this period is significant. But before taking measurements and counting, you should make sure that your baby matches the indicators of a full-term baby:

• Childbirth took place at 38-40 weeks of pregnancy.
• Height is at least 45 cm with a weight of 2.5 kg.
• Head circumference - from 34 to 36 cm.
• Body parts are proportional.
• The skin is smooth, tender.
• Hair length from 1 cm.
• Clear rhythmic pulse.
• Developed sucking reflex (you can read in my article).

If a baby was born prematurely, there are separate height and weight indicators for him, depending on which week of pregnancy he was born. Here is a table of height and weight of a premature baby:

Features of increase in growth in the first year of life are as follows:

• On average, over a monthly period, the baby adds 3 cm.
• The total increase for the first year of life should be at least 25 cm. Thus, the normal figure for a one-year-old baby is from 74 to 76 cm.
• Children grow more intensively in the first months after birth, after which this process slows down. So, in the first 3 months, the increase will be 3.5 cm monthly, from 3 to six months - 3-2.5 cm, from 7 to 9 - about 1.5 cm, from 9 to a year - 1 cm.
• Important is not only the overall increase in height, but also its correlation with weight and proportionality of body parts.

For physicians, an indicator of the normal development of the crumbs is not so much its growth as the circumference of the head. If the head is large and disproportionate to the body, doctors may suspect hydrocephalus, a buildup of fluid in the brain.

From 2 to 17 years old

When a baby turns one year old, parents, as a rule, pay little attention to how much his growth is within the normal range. However, before the onset of puberty, this indicator is no less important than in the first months of life.

After a year, the growth of children is planned to slow down. Up to 2 years, the baby grows on average by 9-12 cm, depending on gender and other factors. Up to 5 years, its growth will increase by only 20-22 cm.

By the age of 10, the average height of a boy is 138-139 cm. From 11 to 17 years old, during puberty, the growth of girls slows down, while in boys, on the contrary, it increases after 12-13 years. By the age of 17, the average figure for a girl will be 155-160 cm, for a boy - 166-171 cm.

How to determine the height of a child?

To determine how tall your baby is up to a year old, you will need a centimeter tape or a meter ruler:

1. Lay the baby on the crib with the back of his head resting on a hard surface.
2. Stretch your legs and place your feet at a 90 degree angle.
3. Mark where the heels end.
4. Raise the child and measure the distance from the mark to a hard surface.

If your child is already able to stand, to measure height, place him near the wall so that his heels touch a hard surface. Then take a hard ruler and place it against the child's head so that it forms a right angle with the wall. Make a mark where they meet and measure the distance from the floor to the mark.

After measuring the height of the child, be sure to pay attention to the indicators of his weight.

Baby's weight by month

WHO strongly recommends that parents pay attention not only to the growth and proportionality of body parts, but also to weight gain. Many parents believe that the more the baby weighs up to a year, the better. But this statement is fundamentally wrong. Unhealthy obesity can occur in both adolescents and infants, especially those who are bottle-fed.

Up to a year

For children under one year old, the weight rate is determined by months, and it should be noted that artificially fed children gain weight much faster:

• 1 month. During this time, the child gains an average of about 0.6 kg. To maintain normal developmental indicators, it is ideal if mommy feeds the baby every 3 hours. The volume of the mixture consumed ranges from 80 to 120 ml per feeding.
• 2 month. During this period, the increase will be about 0.7-0.8 kg. The intervals between feedings can be increased up to 3.5 hours. If in the future you decide to wean your baby from feeding at night, keep in mind that his weight will begin to decrease.
• 3 month. An increase of 0.8 kg is maintained. The intervals between feedings remain, but it should be borne in mind that up to 3 months the baby is disturbed by intestinal colic, so the appetite may decrease.
• 4 month . The child gains an average of 0.75 kg, and then the figures will decrease.
• 5 month . By the end of the fifth month, the baby already weighs 0.7 kg more.
• 6 month . In six months, Krokha adds 0.65 kg. During this period, complementary foods in the form of vegetable purees begin to be introduced, which can replace one feeding.
• 7 month. Body weight increases by 0.6 kg. At seven months of age, babies can be given gluten-free cereal in the morning.
• 8 months. The weight gain is about 0.55 kg. A variety of vegetables, lean meat, cereals, egg yolk are introduced into the baby's menu.
• 9 months . The weight gain is half a kilogram. Purees from several components, fermented milk products appear on the menu.
• 10 months . The baby weighs 0.4 kg more than last month. He already tolerates fresh fruit well. You can add butter or vegetable oil to cereals.
• 11 months. The mass increases by 0.4 kg. The menu can include low-fat fish.
• 12 months . The increase in mass occurs by 0.35-0.4 kg.

The following chart will help you determine if your baby is developing normally:

• For the first half. Multiply 800 by the number of months for the calculation period and add the weight of the crumbs at the time of birth.
• In the second half. M + 800 × 6 + 400x (N-6), where M is the birth weight, N is the number of months.

After a year

In the future, for girls and boys, not only the indicators prescribed by WHO will be important, but also the body mass index, which shows whether the weight is insufficient, normal or overweight. To determine the mass index, you need to divide body weight by height.

Based on the indicators proposed by WHO, it should be taken into account that they are averaged, and slight fluctuations in one direction or another are acceptable. Parents need to sound the alarm if the weight values ​​are significantly underestimated or overestimated.

At low rates, it is recommended to reconsider the diet and daily activity. For example, if up to 5 years old the baby was steadily gaining weight, and by the age of 6 he began to lose weight dramatically, the changes may be associated with preparation for school and stressful conditions, a violation of the usual daily routine.

For babies up to a year, vomiting, leading to dehydration, can become a dangerous phenomenon. The problem may arise in connection with improperly selected nutrition, diseases of the gastrointestinal tract, and the nervous system. In this case, you should definitely see a doctor.

In adolescence, boys, as a rule, have a pronounced thinness associated with intensive growth. Girls, on the other hand, should eat more plant foods, since during the period of hormonal maturation, there is a high probability of becoming obese.

Deviations from normal body weight at any age in a child should be a signal to parents that it is time to sound the alarm and seek medical help if you cannot help the baby on your own.

At the pediatrician's appointment, each baby up to a year is weighed monthly and measured for height. Why is it so important for doctors to know how a child is growing and how much he is gaining weight? What do these parameters say, and what are the anthropometric norms for children of different ages?

Where did the weight and height indicators for children come from and why are they needed?

Anthropometric data of a child are one of the main indicators of the physical development and health of children. Significant deviations from the normal values ​​​​of height and weight in a child almost always indicate the development or presence of certain diseases. So, if a child under one year old with adequate nutrition does not gain weight well, then this may be one of the symptoms of rickets, anemia, immunodeficiency states, diseases of the endocrine or central nervous systems.

A significant growth retardation may indicate a lack of somatotropin growth hormone in the body, and a clear excess weight with normal growth and proper nutrition may indicate disorders in the adrenal glands, thyroid gland, and even the development of a brain tumor.

In order to detect and start treating such formidable diseases in time, doctors carefully monitor the anthropometric indicators of children from birth. Development standards are compiled by the World Health Organization on the basis of many years of research. In addition to the average standard indicator for each age, the limits of the norms were also calculated. Weight and height above this limit is considered high, and below - low. It is for such children that doctors begin to observe especially closely.

WHO table of height and weight for girls under 1 year old

According to the norms, a healthy full-term girl is born with a height of 49.2 cm and weighs 3.200 g. This is the average. The lower limit of the norm for a newborn is a height of 47.3 cm and a weight of 2.800 g, and the upper limit is located at values ​​of 51 cm and 3.700 g, respectively. Values ​​outside the lower and upper limits of the norm are marked as very low or too high. Doctors will observe such a newborn and, possibly, additionally examine it.

During the first month, the newborn should grow by 4.5 cm and gain a kilogram. The lower limits of the norm for a monthly girl will be 51.7 (height in cm) //3.600 (weight in grams), and the upper limits - 55.6 //4.800.

Normal indicators for a two-month-old baby: 57.1 cm and 5.100 gr. The lower limit of the norm is 55 // 4.500, and the upper limit is 59.1 // 5.800.

By three months, girls grow to 59.8 cm and weigh 5.900 grams. Low for a three-month-old baby is considered to be less than 57.7//5.200, and high is more than 61.9//6.600.

By five months, girls should grow to 64 cm and weigh 6.900 grams. Low rates - parameters less than 61.8//6.100. Indicators 66.3 // 7.800 are the upper limits of the norm for a five-month-old girl.

The age of 6 months is considered an important milestone in a child's development. A six-month-old girl should grow to 65.7 cm and weigh 7.300 g. The lower limit is 63.5//6.500, and the upper limit is 68//8.300.

A seven-month-old baby grows to 67.3 cm and weighs 7.600 grams. Scores below 65// 6.800 are considered low, while scores above 69.6 //8.600 are considered high.

At eight months, the norms are: height - 68.83 cm, and 8 kg - weight. The lower limits of the norm: 66.4//7000, and the upper ones - 71.1//9000.

By nine months, growth should be 70.1 cm, and the baby should weigh 8.200 grams. Low values ​​at this age are values ​​less than 67.7//7.300, and high values ​​are more than 72.6//9.300.

A ten-month-old baby, according to the norms, should be 71.5 cm tall and weigh 8.500 grams. The lower limits of the norm for ten months are 69//7.500, and the upper frames: 74//9.600.

By eleven months, a normal girl grows to 72.8 cm and weighs 8.700 grams. Indicators less than 70.3//7.700 are considered low. High will be indicators exceeding 75.3//9.900.

By the year, according to the norms, girls should grow up to 74 cm and weigh 9,000 grams. The parameters 71.4 //7.900 are considered the lower limit of the norm, and 76.6 //10.100 are considered the upper limit.

WHO table height and weightfor boys up to 1 year

The norms for boys are different from the norms for girls, as boys are usually born slightly larger. So, a healthy full-term newborn boy is usually born with a weight of 3.300 grams and a height of 49.9 cm. These figures are considered normal. The lower limit of the norm for a newborn is a height of 48 cm and a weight of 2.900 g, and the upper limit is at 51.75 cm and 3.900 g, respectively.

For the first month, the baby should grow by 4.8 cm, and gain 1200 gr. The lower limits for a monthly boy will be 52.8 (height in cm) // 3.900 (weight in grams), and the upper limits - 56.7 // 5.100.

Normal indicators for a two-month-old peanut: 58.4 cm and 5.600 gr. The lower limit of the norm: 56.4 // 4.900, and the upper - 60.4 // 6.300.

By three months, boys grow to 61.4 cm and weigh 6,400 grams. Low readings will be below 59.4// 5.700, and high readings above 63.5// 7.200.

Average height and weight for a four-month-old boy: 63.9 cm and 7000 gr. The lower frames of the norm are 61.8 // 6.300, the upper frames are 66 // 7.800.

By the age of five months, the boy should grow to 65.9 cm and weigh 6.900 grams. Low rates - parameters less than 63.8// 6.100. Indicators 68 //7.800 are the upper limits of the norm for a five-month-old baby.

By six months, the baby should grow to 67.6 cm and weigh 7.900 grams. The lower limit is 65.5//7.100, and the upper limit is 69.8//8.900.

A seven-month-old boy grows to 69.2 cm and weighs 8.300 grams. Below 67// 7.400 will be considered low, and above 71.3 //9.300 will be considered high.

At eight months, the average indicators for a boy are: height - 70.65 cm, and 8.600 g - weight. The lower limits of the norm: 68.45//7.700, and the upper ones -72.85//9.600.

By nine months, the baby should be 72 cm tall and weigh 8,900 grams. Low values ​​will be less than 69.65// 8.000, and high values ​​will be more than 74.3//9.900.

A ten-month-old boy should normally be 73.3 cm tall and weigh 9.200 grams. The lower limits of the norm at this age are 71//8.200, and the upper limits: 76//10.200.

By eleven months, the normal baby grows to 74.5 cm and weighs 9.400 grams. Indicators less than 72.2//8.400 are considered low. High will be indicators exceeding 76.8//10.500.

In a year, according to the norms, boys should grow up to 75.8 cm and weigh 9.700 grams. The parameters 73.5 //8.700 are considered the lower limit of the norm, and the upper limit is 78//10.800.

Growth and weight table for girls from 1 to 10 years old

The growth of children begins to slow down as soon as the babies turn one year old, therefore, for children from one to three years old, the norms are no longer determined monthly, but every three months. For children from 3 to 7 years old - once every six months, and for children aged from seven to ten years - the norms change once a year.

By the age of one and three months, a girl should normally grow to 77.5 cm and weigh 9.600 grams. The lower limits of the norm: 74.83 (height in centimeters) and 8.500 (weight in grams), the upper limits: 80.3 / / 10.900.

Table of height and weight for teenage girls

In adolescents, anthropometric data are monitored once a year. For an eleven-year-old girl, the averages are 144.5 (height in centimeters) / / 34.4 (weight in kilograms). Parameters less than 136.2//27.8 are considered the lower normative limits, and parameters more than 153.2//44.6 are considered the upper ones.

Average height and weight for a twelve year old: 150//40.7. Lower limit of the norm: 142.2//31.8, upper: 162.2//51.8.

A thirteen-year-old girl normally has the following indicators: 155.8//44.3. Lower data bar: 148.3//38.7, upper: 163.7//59.

At the age of 14, the average data for a girl: 159.5 / / 53.1. The lower limits of the norm: 152.6//43.8, upper: 167.2//64.

By the age of fifteen, the average height of girls reaches 161.6 cm, and the average weight is 55.5 kg. Lower limit of data: 154.4//46.8, upper: 169.2//66.5.

Table of height and weight for teenage boys

Boys between the ages of 10 and 14 years are slightly behind girls in growth, this is normal, since hormonal changes in boys begin a little later than in girls. But after fourteen years, guys begin to grow more intensively than girls, and by the age of 15 they overtake them in terms of growth.

In adolescence, anthropometric indicators significantly depend on genetic predisposition, therefore, when monitoring the physical development of adolescents, it is recommended to focus not so much on the average, but on the limits of the norm indicated for each age and on the child's heredity. So, if the father of a young man has a height of 190 cm, then the height of 182 cm of the teenager himself at the age of 15 can be considered the norm in this case.

For an 11-year-old boy, the average figures are: 143.5 (height in centimeters) / / 35.5 (weight in kilograms). Parameters less than 134.5//28 are the lower limits of the norm, and parameters greater than 153//44.9 are the upper limits.

Average height and weight for a twelve-year-old teenager: 149 / / 39.8. From the border: 140//30.7, to: 159.6//50.6.

A thirteen-year-old teenager normally has the following indicators: 155.5//44.3. From the border: 145.7//33.9, to: 166//59.

At the age of 14, the average indicators are 161.9//49.7. From the border: 152.3//38, to: 172//63.4.

By the age of fifteen, the average height of the guys is 168 cm, and the weight is 55.5 kg. From the border: 158.6//43, to: 177.6//70.

Average height and weight for sixteen-year-old boys: 172.3 / / 66.9. From the border: 163.2//48.4, to 182//76.5.

At seventeen, the average height and weight are 176.6 / / 66.9. From the border: 166.7//54.6, to: 186//80.1.

Video "The height and weight of the child, Dr. Komarovsky"

The first thing that happy relatives are told after the birth of a newborn is the main parameters of his body, that is, height and weight. Together with the circumference of the head and chest, they are immediately recorded in the baby’s medical record, and from this very moment, the young mother will have to visit the local pediatrician every month, who will be the most important indicators of the baby’s development, tracking their dynamics.

Why is the height and weight of the child so important for both parents and doctors?

Why monitor the growth and weight of the baby?

Body weight, height, as well as head and chest circumferences are parameters by which doctors can assess the physical development, and, accordingly, the state of health of the newborn. The average norms for newly born babies are the following figures:

• height: 46-56 cm;
• weight: 2500-4000 g;
• chest circumference: 32-34cm;
• head circumference: 34-36 cm.

In the first few days after birth, the baby loses about 10% of its original weight. But by the day of discharge from the hospital, the weight of healthy children usually returns to normal, and the corresponding figure is necessarily recorded in the medical record - the district doctor will start from it, calculating the proper weight and height of the child.

If the child is gaining weight well, the doctor will carry out a control weighing once a month, and if there are any problems, once every two weeks.

What determines the weight gain in a child?

Any deviations from the above norms, of course, are very frightening for young parents, but this situation is far from always a reason for panic.

The fact is that the main parameters of the baby and weight gain depend on a number of different factors that also need to be taken into account.

• Heredity. The body weight of a newborn is largely determined by genetics: for example, miniature, thin parents rarely have children with a lot of weight.
• Health status. Our grandmothers consider excellent appetite a sign of good health, and in the case of babies, this is quite acceptable. Even if the child has a common cold, he will still be capricious and refuse to eat.
• Mother's health status. If during the period of bearing a child, a woman suffered any diseases, this may affect the body weight of the child. The same applies to the lactation period - for example, nervous stress directly affects the quantity and quality of milk.
• gender. Boys tend to be taller and heavier than girls.
• Nutrition for women during pregnancy and lactation. There is a direct relationship between the mother's diet and her baby's body weight: if she consumed high-calorie foods in large quantities, the child may be born overweight. If a woman does not eat well while breastfeeding, her milk will be watery and less nutritious, which can affect the baby's weight. About the nutrition of a woman during breastfeeding, read
• type of feeding. Babies who are breastfed often gain weight a little slower than "artificial" ones. But children who are fed on demand have been observed to have more consistent weight gain than those fed on a schedule.
• Appetite. Each baby, like any person in the world, has its own characteristics, in particular - good or bad appetite.

Modern pediatricians say that the norm of weight and height of children is indicative, therefore, slight deviations in one direction or another, with the baby feeling normal, can be considered acceptable.

Height and weight of a child up to a year

There is a special table of height and weight for children under one year old, which was developed by WHO experts - it is from it that we can talk about excessive or insufficient weight gain in a child.

Age, months	Average increase, gr	Norms weight, gr		Norms growth, cm
		min	max	min	max
1	750	3600	4800	51,7	55,6
2	750	4500	5800	55	59,1
3	750	5200	6600	57,7	61,9
4	700	5700	7300	59,9	64,3
5	700	6100	7800	61,8	66,2
6	550	6500	8200	63,5	68
7	550	6800	8600	65	69,6
8	550	7000	9000	66,4	71,1
9	550	7300	9300	67,7	72,6
10	350	7500	9600	69	73,9
11	350	7700	9900	70,3	75,3
12	350	7900	10100	71,4	76,6

In addition, the proper weight of the child can be calculated using the formulas:

For children up to six months

body weight = birth weight + 800 N, where N is the number of months.

For children aged 6-12 months:

But starting from 6 months, when weight gain decreases slightly, the formula becomes more complex and looks like this:

body weight = birth weight + 800 6 + 400 (N-6), where N is the number of months (from 6 to 12).

That is, changes in the body weight of the baby should fit into the following framework:

• in the first days of life, the weight of the baby can decrease by 5-10%;
• in the first month of life, an average baby gains about 20g per day;
• in the second month, the child gains approximately 25-30g;
• by the age of 5-6 months, the initial weight of the baby should double;
• upon reaching the age of one year, the weight of the baby should increase by about 3 times;
• from the age of two until puberty, the body weight of the child increases by about 2 kg per year.

As for the growth of the baby, this indicator is more stable than weight, so special formulas in this case are not required - the growth of the baby increases by an average of 3-4 cm every month.

Circumferences of the head and chest in a child

Another indicator that the district pediatrician will definitely measure at each visit is head circumference.

In newborn babies, the head circumference is about 34 cm and 2-5 cm more than the chest circumference, which is why babies usually look very touching: a large head and a small, fragile body. Subsequently, the volume of the chest begins to increase a little faster and gradually outstrips the head; if this does not happen, then the doctor may suspect the presence of some pathologies.

It should be noted that it is not the numbers themselves that matter, but the dynamics of their change.

In order to assess the development of a child, modern specialists use the so-called centile tables, based on the average indicators of a certain number of children (for example, 100, 1000, etc.). Indicators in the range of 25-75 centiles are considered the norm - if the numbers fall in the range of 3-10 centiles, then the baby may need additional research.

Why is my child not gaining weight?

Of course, the height and weight of a child up to a year by months are important indicators of its development, but in addition to numbers, parents should pay attention to the well-being of the baby. There are several criteria by which you can determine whether a child is getting enough milk and how well his digestive system is working.

• Feeding frequency. The baby should eat at least seven to eight times a day.
• Activity. If the child is cheerful and active, develops according to age, is interested in the outside world and has a pink, healthy complexion, then there is most likely no reason to panic.
• stool frequency. On average, a baby should empty the intestines four times a day, and the older he gets, the less often he has such a need.

If the baby is lethargic and capricious, gains less than 16-18 g per day, sleeps too long or too little, his urine is dark and is excreted in small quantities, vomiting and fever are noted, which means that parents should consult a doctor.

For signs of undernutrition or overnutrition in a child, read

There can be several reasons for poor weight gain, and the most common of them is a violation of the diet of both the child and the mother: an unbalanced diet, wrong.

In addition, children who have gastrointestinal pathologies, infectious diseases, worms, neurological problems, and much more can gain weight poorly.

Why is my baby gaining weight too quickly?

Chubby, rosy-cheeked children usually do not cause concern among parents and pediatricians, but in fact, not everything is so simple. Excess weight in infancy can lead to obesity, and consequently, to metabolic disorders and serious diseases in older age.

Unlike obese adults, overweight babies do not require a special diet, but the mother is advised to review and adjust the diet.

You need to feed the baby only when he is really hungry - if he is hurt or just naughty, you need to try to calm him down in a different way, otherwise the child will “seize” stress all the time.

"Artists" who gain weight too quickly may need a different, lower calorie mixture; in addition, you need to make sure that the rules for diluting mixtures are observed - an insufficient amount of water significantly increases their calorie content.

About how much mixture a child should eat, read

The height and weight of a child up to a year old are indeed very important indicators of his development and health, but you should not try to fit the baby to generally accepted standards.

If he is healthy, cheerful, active and has a good appetite, then the reasons for deviations from the norm are most likely the features of his constitution and over time everything will return to normal.

As each child develops, it grows and gains weight. Parents who are concerned that the baby grows “correctly” always pay attention to “normal” indicators of body weight and height, focusing on the average data given in the tables of the World Health Organization. When answering the question of how much a child of a certain age should weigh, it should be borne in mind that the body of each person has individual characteristics. That is, in order to understand that everything is in order with the child and he is growing normally, you need not only to compare his parameters with the standard, but also take into account their ratios.

The ratio of the parameters of growth and body weight of the child

The concept of "body mass index" is well known to many parents - especially mothers who are watching their figure. To assess the harmonious development of the child and identify possible deviations in height and weight, you will also need to calculate BMI.

It is important to remember that the norm indicators for a baby differ from those calculated for the adult population. The normal BMI of an adult is no more than 25; for children, a similar index can vary between 13-21. BMI is calculated to diagnose the following conditions:

1. obesity requiring treatment;
2. overweight;
3. slightly increased weight, which is within the permissible range of normal fluctuations;
4. normal weight (see also:);
5. underweight;
6. exhaustion requiring treatment.

Features of the first year of a baby's life

Dear reader!

This article talks about typical ways to solve your questions, but each case is unique! If you want to know how to solve your particular problem - ask your question. It's fast and free!

In the first twelve months of a child's life, the indicators of his growth and development are directly related to the characteristics of feeding. In accordance with WHO guidelines, a breastfed child with a birth weight of 3.3 kg (boy) or 3.2 kg (girl) is taken as a reference when developing the table. According to the growth rates, the “starting indicators” are taken to be 49.9 cm and 49.1 cm, respectively.

If the baby was born with less body weight and height (this is often found in children born prematurely, as well as in those born from short parents), then there is no need to worry that after a month or two he “lags behind” from tables.

Until the age of one, it is not the correspondence of height and weight to the table that is decisive, but their change over time. If the child is systematically gaining weight and growing, then everything is in order with him, and there is no reason to panic.

Height and weight of boys

The characteristics of the weight and height of male babies until they reach the age of one are determined according to the same principles as for girls. Of decisive importance for monitoring the condition and development of the child is the monthly weight gain - that is, you need to compare the baby first of all with him, as he was a month ago.

Age, months	Weight in grams			Height, cm

Indicators of a child under 10 years old

The period from birth to reaching the age of 10 is characterized by the rapid growth of the child. However, if up to a year old the baby grew noticeably and “heavier” almost every day, at an older age it will grow a little more slowly.

This is due to changes in metabolism and the growing activity of the baby: the baby spends much less energy and calories on outdoor games than the little one, who has already learned to walk and run, and is now actively learning about the world around him.

Height and weight of a 1 year old baby

If we turn to the average values, it can be noted that during the first year of life, the baby gains about 6-7 kilograms. At the same time, most of the "increase" falls on the first six months of life, when the child adds about 700-800 grams in one month. With proper care, healthy small babies by 6-7 months can “catch up” in weight with their peers who were born with an average body weight.

The weight of a one-year-old child is considered normal if its value is in the range between 8 and 12 kg. In this case, the increase in height will be about 25 cm. The height of a child at 1 year old is approximately 75 cm ± 6 cm.

Height and weight from 2 to 3 years

Between two and three years, the baby is still growing. However, there is less and less quiet rest and meals in his daily routine, and the amount of time devoted to outdoor games is steadily growing. Normally, in the third year of his life, the child will gain about two to three kilograms (that is, it will weigh 11-15 kg) and grow by 9-10 cm.

Height and weight from 4 to 5 years

The average weight of a harmoniously developed 4-year-old baby, according to WHO, is about 16 kg, while a deviation of 2-3 kg up or down is considered a variant of the norm. The growth of a baby of this age is 102-103 cm. By his fifth birthday, a preschooler will recover by about 2 kg and grow by 7 cm.

Height and weight from 6 to 7 years

If you put a healthy six-year-old baby on the scales, and a value from the range of 18-23.5 kg is displayed on the screen, then it fully complies with the standards developed by WHO. By his seventh birthday, an older preschooler (or a younger schoolboy) will become 2-3 kg heavier. According to the growth rate, it will grow by about 5 cm.

Pivot table with parameters from 1 to 10 years

For those parents who are worried about the development of their baby, it will be useful to familiarize yourself with the summary table of height and weight of children, compiled according to WHO. Here are the average height and weight for children of both sexes aged 1-10 years. The parameters of the baby do not have to exactly match the values ​​\u200b\u200bgiven in the table - a deviation of 2-3 kg and a few centimeters in any direction is considered a variation of the norm.

It should also be taken into account that girls grow intensively after 10 and up to 12 years, in boys a jump is observed at an older age - after 13 and up to 16 years. Girls gain height on average up to 19 years, and boys - up to 22 years.

Indicators for children aged 11 to 18

Indicators that are considered normal at the age of 11-18 years are distinguished by their wide range. This is the period of the onset of puberty, when global changes occur in the body of a teenager. Parents must prepare their growing son or daughter not only physically, but also emotionally.

It should also be borne in mind that it is not recommended to follow a diet for weight loss at this time - a lack of necessary elements in the period before the age of 18 can lead to serious problems in the future.

The norms of height and body weight of children are presented below.
