Minimum weight gain in infants. What is the normal weight for a newborn
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 one 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.
Average height and weight for a four-month-old girl: 62.1 cm and 6.400 gr. The lower limits of the norm are 59.9//5.700, the upper frames are 64.3//7.300.
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.

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.

Perhaps the most important indicators of a child at birth are the length and weight of his body: these values \u200b\u200bare the first entries in the first baby documents: a medical card and a tag. How much these parameters should change in 12 months will help you find out the table of height and weight of children up to a year.
Norms of weight and height in newborns
For babies born at term (from 38 to 42 weeks), the range of 46-57 cm is considered normal height, and weight - 2600-4000g. If the baby is premature, or born with pathologies, as well as in the case of multiple pregnancy, these figures can be significantly lower. So, for twins and triplets, weight up to 2 kg is also not considered critical.
When the baby is discharged from the hospital, he weighs a little less than at birth, and this is also the norm: in the first days, up to 8% of the weight is lost. But only when the weight stops falling and begins to increase, the baby is ready for discharge. The increase in height and weight of newborns is monitored by a pediatrician, which is why it is so important to visit him every month.
Increase in height and weight of crumbs up to a year
For the first six months, the baby adds 500-800g monthly on average. And every month at the pediatrician's appointment, the ruler shows from 2 to 5 cm of growth.
In the second half of the year, the rate of weight gain slows down as the child becomes more active.
During the year, the baby grows by an average of 25 cm, and the weight increases approximately three times.

centile tables
It is much more accurate to assess whether the development of the baby is harmonious, centile tables help.
The columns of the tables contain quantitative limits for weight and height indicators for a certain percentage of infants; averages are considered to be intervals from 25% to 75%.
If the parameters of your baby fit into these intervals, then this can be called the norm. Columns before and after these corridors (10%-25%) and (75%-90%) are considered as deviations from the norm in the smaller and larger sides, respectively. If the baby’s indicators are included in the most extreme columns, this is an occasion for an urgent appeal to specialists.
It is very important that both the height and weight of the child are included in the same centile corridor (+/- one column), such a height-weight ratio is considered correct. To do this, compare the data that the child’s growth table shows by months up to a year with the data from the baby’s weight table up to a year, and evaluate the result.

How to measure height and weight correctly?
Sometimes the wrong measurement of height and weight causes young mothers and fathers to panic. And sometimes even the doctors themselves make mistakes: the baby slipped a little on the stadiometer, or did not straighten the leg to the end - and here it is, the error! They forgot to take away the weight of the diaper when weighing in the previous month - so the weight loss came out next!
You need to measure the weight and length of the body regularly and write it down on a tablet for up to a year by months (you can do it yourself), such records will help you independently assess whether your baby is developing correctly.
To measure your baby's height at home, prepare a pencil and a large wooden ruler or measuring tape. It is better if the baby is naked: a cap and socks can give an error in measurements, and even a diaper, due to its rather big, in general, thickness, raises the baby’s ass, the back bends slightly, which can also cause inaccuracies.
Place the baby on a hard surface (ideally a changing table) so that the head rests on a hard barrier perpendicular to the surface: the side of the table, the head of the bed, the wall. Stretch the legs, straightening them at the knees. Mark a line under the heels (not fingers!). Measure the distance from the headboard to the dash.
Scales are needed to measure body weight. In general, it is very useful to purchase them as dowry crumbs. Scales need special, children's, electronic, with a convenient bowl.
Undress the little one. Put a thin diaper on the scales, drop its weight so that the scoreboard shows zero. Place your child on the scale, distributing the weight evenly on the bowl. Wait until the numbers stop motionless.
Never use a steelyard scale while placing your baby in a bag or tied diaper for measurements. This method of measurement is very dangerous, you can drop the child. And it's still not possible to achieve the exact result.
Do not be discouraged if the weight and height of the baby do not reach the average table! It is important that they match each other. And if the child is too small or too large, take a closer look at yourself: maybe he went to dad or mom?
Children's height and weight are rapidly changing quantities and are a very important indicator of a child's overall development. Sometimes it seems to parents that their child is growing by leaps and bounds: the recently bought jacket has already become cramped, the new shoes are already too small, and the little one has stretched out and become very large. But sooner or later, any parents ask themselves questions - what height and weight should a child have at his age? What parameters are considered normal?
To answer such questions, the World Health Organization (WHO) has developed tables of normal height and weight for children from birth to 17 years of age. These standards are suitable for assessing the development of a child of any nationality and do not depend on social status and place of residence.
It is worth noting that, according to WHO, children who are breastfed gain weight more slowly than their peers who are bottle-fed. However, the table takes into account averages, therefore it is applicable to all types of feeding.
The growth rate of a child depends on his age. As you know, the child begins to grow even in the womb and at birth, his height is 46-55 cm. In the first year of life, the child grows very quickly - on average, by about 25 cm. grows by 5-7 cm per year. In adolescence, in some years, a sharp jump in the growth of the child is possible (by 10-15 cm per year), which is normal and is associated with puberty.
Weight norms are usually proportional to height. The child actively gains weight in the first year of life, then the weight gain slows down significantly and becomes stable until the age of 17-18, depending on individual developmental characteristics.
Norms of growth and weight of children up to 1 year
According to WHO developments, the normal range for both boys and girls is allocated in the table of height and weight. Indicators "low" and "high" are a signal for parents to consult a doctor. If the real height or weight deviates significantly from the norm, this may be the result of a systemic disease or an unhealthy lifestyle - you should immediately consult a doctor and examine the child.

Good afternoon, my dear readers - moms and dads! You just had a baby, I congratulate you on this! Exciting moments, joy, anxiety and uncertainty - all in one. For some time, these feelings will prevail over you, but still you need to tune in to a new way and life will go back to normal. Along with thousands of questions, in the head of young parents there is an urgent question about how much a newborn should normally weigh and how soon he should gain weight and height. The classic table of newborn weight gain by months will help you with this.
Girls and boys are usually born in different weight categories: boys tend to be slightly larger. However, how much should a newborn weigh?
The weight of a baby at birth depends on the following factors:
- Gender of the child;
- Date of birth;
- The composition of the parents;
- Mom's nutrition during pregnancy;
- The presence of fetal pathologies or problems with the passage of pregnancy;
- The presence of bad habits in the mother during pregnancy.
A healthy full-term boy weighs normally (on average) - 3.5-3.7 kg. Girl, respectively 3.2-3.5 kg.
In the maternity hospital, a newborn is weighed two control times - immediately at birth and at discharge.
This is done in order to compare how much the baby will lose in weight over these few days. And there will certainly be losses.
2. Why does the baby lose weight after birth?
Physiological weight loss of a newborn is a normal phenomenon, in no case should you be afraid of this.
Natural weight loss in a newborn comes from:
- Natural fluid loss through the skin;
- Sudden change in diet;
- The amount of food in the first days;
- Stress due to environmental change.
After the birth of a child, a shock occurs, a real stress, and this is understandable. This shock is one of the reasons for the slight weight loss. Nutrition also becomes new for the baby, the umbilical cord no longer supplies him with all the necessary substances, you have to “get” food on your own, which are still so fragile.
In the first three days, the mother adjusts lactation, colostrum begins to stand out, milk will arrive later. This colostrum is not enough for the baby to eat. Despite its quantity, the nutritional properties of colostrum are about the same as those of concentrated milk, and even more.
All these factors lead to the fact that the baby in the first days of life slightly loses weight. As a rule, he makes up for this weight loss very quickly already in the first month.
When discharged from the hospital, the weight of the baby is again measured. The allowable amount of weight loss from birth to discharge from the hospital is 5-10 percent. From this, and count the weight gain by week and by month.
3. Norms of weight gain and growth of a newborn up to a year by months
Normally, in the first 4 months, the baby grows most intensively. Every month it grows by 2-3 cm, the rate of weight gain per month, on average, is 600-800 gr.
By 6 months, the baby will already weigh twice as much as it was when it was discharged from the hospital, and by the year - three times.
Do not forget that weight gain, as well as height, depends on the initial build of the newborn. An increase in a large child may not go the same way as in a small one, everything is individual.
Meanwhile, I present to you a table with averaged data on the increase in height and weight of babies up to a year by months: 
4. Factors affecting weight gain in newborns
The schedule of weight gain and growth in girls and boys is somewhat different. As a rule, girls gain more weight and height in the first month than boys. In the following months, the curve of the ratio of height / weight for both girls and boys goes smoothly and proportionally.
Weight gain in newborns is affected by:
- Type of feeding - breast or artificial;
- Feeding method - by the hour or on demand;
- milk quality;
- Baby health.
So, if the baby is artificially fed, he will gain more weight than the one that is breastfed.
Feeding on demand also results in more weight gain than timed feeding.
If the baby is healthy and adapts well to the new environment, he will develop correctly, that is, gain weight and grow within the normal range:
If the baby is underweight in the first two months, the pediatrician will draw your attention to this and may prescribe supplementary feeding.
It happens that the mother does not have enough milk, then the baby is constantly hungry and does not grow well. By choosing a supplemental formula, you can easily fix this problem.
With a critically low weight of the baby, an examination is prescribed to identify possible pathologies. After six months, weight gain and height is slower and depends on the baby's nutrition. At this time, complementary foods are introduced, so it becomes easier to regulate the amount of food that the baby receives per day:
Also, if the baby is sick, there is a lack of weight. With recovery, everything usually falls into place. Dear moms, do not worry, any deviations in weight gain or height are correctable. The main thing is to see your pediatrician and lead a healthy lifestyle.
And in this video you can see what a neonatologist says about weight gain in babies:
For today I say goodbye, do not forget to subscribe to updates and share information on social networks.
Almost every mother is interested in the correct physiological development of her child. During the first year of life, doctors check the height and weight of the child by months according to a certain table provided by WHO. But all babies are individual, and their performance may slightly lag behind or exceed the data of such tables. There are a number of characteristics that every parent should study in order to know for sure whether their child is developing correctly.
Each child is individual, and their weight and height may differ slightly from the table. They can be influenced by many factors. The main ones are:
In the first months of a child's life, growth and weight indicators can change both up and down. Minor deviations from the norms adopted by WHO should not frighten parents. After all, if the child is completely healthy, he is active and alert, has no problems with stool, then these indicators are ideal for him. But if these deviations are too large, you should consult a pediatrician for advice.
Calculation rules
Standards for the growth and development of the child are calculated through many studies and experiments, so minor discrepancies are considered natural and unprincipled. We should also not forget that there is a genetic factor that has a significant impact on these indicators.
If both parents are rather large people, then with a high degree of probability they will have a child who will be ahead of other babies in height and weight. And people with short stature almost always give birth to small children who will lag behind in height and weight from age characteristics. According to generally accepted standards the standards are:
“In medicine, there is a certain formula that helps determine the ideal weight of a baby up to six months: M + 800 x N. Each letter has a specific meaning. So, M is the weight of the newborn in kilograms, N is the age at the weighing period.
But after six months, the formula changes significantly: M + 800 x 6 + 400 x (N - 6). Here M is the weight of the child in kilograms at birth, 800 x 6 is the norm that should be gained by the age of six months, N is the number of months that have passed after six months.
However, pediatricians judge the correct development of the baby not by tables or formulas, but by the ratio of weight and height. For girls, the acceptable height at birth is 43.5 cm, and for boys - 53.4 cm.
Weight norm
Specialists have standards for the weight of the child by months - table for boys. All results in it are approximate and may vary depending on the physical parameters of the child and his diet.
The month-by-month baby weight table for girls is also indicative. There may be minor changes in one direction or another and remain normal:
Details by month
On the Internet, there are many graphs and criteria for weight gain and growth in infants. For most mothers, they are the main ones in determining the correct development of the baby. But this is fundamentally wrong, because each baby develops according to its physical capabilities, and deviations in all parameters are very likely, so young parents should know the approximate criteria that specialists are guided by.
Child growth chart by months to a year can be roughly written like this:
“A similar table of weight and height of a child by months is used by most pediatricians. It helps to calculate how much the baby should gain kilograms in six months and in a year. However, you should not focus only on the calendar, because each baby is individual and can develop in different ways.
Development up to a year
Starting from the seventh month of life, the child gains weight somewhat more slowly than before six months. The nutrition of the crumbs remains the same, only in the morning breast milk is replaced with gluten-free porridge or mashed potatoes. Gradually, the baby's diet should be diversified. New foods should be introduced in small portions so that the baby can taste the food and determine what he likes and what not. If you give your child a large amount of a new food right away, an intolerance or an allergic reaction may develop.
In the eighth month, weight gain reaches only 500 grams. At this time, the nutrition of the crumbs becomes even more diverse. Meat products appear on its menu. They should also be given, starting with half a teaspoon. At the same time, it is allowed to introduce chicken yolk into the child's diet.
By the end of the 9th month, multi-component purees and fermented milk products should be added to the crumbs' diet. Its weight will increase by 500 g, and height by 2 cm.
By the age of one year, the baby can already be given fish and other adult foods. They should not be ground, but should be cut into small pieces so that it does not choke. Weight should triple from the original at birth.
All these parameters are approximate, and doctors are guided by them when determining how harmoniously a child develops. If they differ from the tabular ones, then parents should not panic, individual development is natural for every baby, it is difficult to fit it into any framework.
