Every pregnant woman already at the end of the term knows the approximate weight of her baby. This is a very important point. After all, even then you can assess the state of health and development of the child. But with his birth the question of body weight becomes more relevant. Moms worry, the baby receives a sufficient amount of milk and whether it is high in calories, then how to diversify the menu or just feed its child. A little later - is he eating well in the kindergarten, is he starving at school. Often children refuse vegetables, dairy products. And with this comes fear and excitement: will it grow, will it gain the right weight, will it get enough vitamins. We suggest that you familiarize yourself with existing regulatory indicators. The weight table of children will clearly demonstrate them.
Body mass index in children
Today, there are certain standards for the weight and height of a baby at birth. Normally, the weight of the newborn ranges from 3 to 3.5 kg. Any deviations are already considered a pathology. However, there is such an important factor as the growth of the baby. Therefore, the surest way to determine the norm is to calculate the index. The mass of the body should be divided by the height squared. In this case, weight is measured in kilograms, and height - in meters.
For example, a boy was born weighing 4 kg. At first glance - a bit too much, but measuring his height, we get 54 cm. Therefore, after calculating the index and carefully examining the child, the doctors were convinced that the baby was developing as expected. The calculation of the index in this case looked like this: 4 / 0.54 2 . The body mass index is 13.7, which, in turn, is included in the values of the WHO table.
A newborn baby does not gain weight immediately after birth, and even vice versa. During the first 3-4 days, its weight may decrease by 100-250 g. But usually by the age of two weeks, babies reach the weight at birth. And in the future, the child should regularly gain weight.
The norm of weight of the child is fixed by the World Health Organization. The table was updated in 2006 taking into account the type of feeding. After all, children on artificial feeding gain weight much faster than babies. Therefore, the weight of children under the age of WHO is determined depending on the nutrition of the baby. It also indicates such important indicators as head circumference and chest circumference.
Norm of weight and height of children: table
Data on the value of height and weight, which are given in the table, are indicators of the development of a child up to a year. It also indicates the minimum and maximum limit values. Deviation from the norm is a good reason to contact a neonatologist or local pediatrician.

The norm of the weight of the child and other indicators
In the first year of life, the baby most intensively grows and develops. Total on average, he will grow by 24 cm and gain 8 kg. The baby’s head will constantly increase in volume: in the first year of life, it will grow by 10 cm. The size of the chest also changes in the baby. After all, all organs are developing, they need more space. The chest girth will expand by approximately 11 cm.
Weight gain is part of the overall development of the child. It will be uniform and normal only if all the relevant conditions for this are met. These include proper healthy nutrition, quality sleep, pastime in the fresh air, active games and just a good mood in the baby.
The children's weight table also exists in a different form and is called the centile corridor. It is an eight-point scale with percentages. In accordance with growth and weight, each newborn receives his first mark.
All children are different
Although growth trends are more accurately determined during puberty, but before that, the development of the child also depends on hereditary data. In a family where mom and dad are short, it is unlikely that a two-meter guy will grow up. But how much it weighs depends solely on the quality of food. Therefore, the diet should be right from infancy.
Children in their second year of life gain weight less rapidly than before. At an older age, the child begins to grow irregularly, this can especially be seen after the summer holidays. By the way, the opinion that children grow up in a dream is fully justified.
Do not forget that boys mature a little slower than girls. A sharp jump in their growth is already taking place in the middle - high school.
Healthy baby - happy mom
Keep track of changes, weigh and measure the baby every month, and a table of children's weights will help you with this. Of course, do not forget that all children are different, and their development is an individual process. And even if all the development parameters are normal, and something bothers you, do not hesitate to resort to a specialist consultation. This is especially true for the smallest, because they still can not answer your questions and concerns. Therefore, let this data become for you nothing more than a pillar and reference material.
