Physical development of children takes place differently, it depends not only on a sex of the child, but also his heredity, the state of health, food and other conditions. Exact values of weight for each age do not exist, nevertheless, statistical data allowed to reveal norms of physical development on which it is convenient to be guided. At considerable deviations from normal indicators speak about problems in development of the child, in other cases it is only individual growth rates.
How many the newborn child has to weigh
There is an opinion that the newborn child is larger, the he is healthier. Nevertheless, the kid weighing from 2.5 kilograms is not considered little at pediatricians, he does not need to quote the strengthened food or other terms of leaving. If the child full-term, is not observed any violations and problems with health, then it is not necessary to consider him less healthy, than his age-mate weighing 4 kilograms. The difference in weight speaks only about differences in the structure of an organism and rates of their development. It does not mean that the small child will surely grow up sickly and thin, just at this stage of development such weight for it is normal. Doctors do not recommend to give to such child more food, it will lead to vomiting.
At normal food and observance of other conditions of care for the kid it will catch up with the peers.
But weight less than 2.5 kilograms already speaks about violations in development, such children are called small and require attention of doctors. Polycarpous pregnancy or prematurity can be the cause of small weight, but it is not a sentence, such child at the correct medical leaving will grow up healthy. The child's weight more than 4 kilograms – too not norm. In certain cases the big weight of the newborn is caused by the fact that mom is sick with diabetes. This disease leads to increase in a fruit during pregnancy, and after the birth at the child the risk is higher to ache with diabetes. Such children are recommended to be shown after the birth to the endocrinologist.
But in certain cases big weight is a hereditary feature: if dad growth under two meters, and mom too quite large, then there is nothing surprising in it.
The child's weight after the birth
Not only the child's weight at the birth is important, but also rates of its increase during life. The first days the kid can lose a little in weight, and it is normal, but in a week it begins to add grams. It is desirable to control the child's weight every month to monitor his development. There are special tables of norms of weight for children of various age and a floor. So, the boy in six months has to weigh about 8 kilograms, and the girl – about 7,200 grams. Rates of an increase of weight are especially high the first year of life, and then gradually begin to decrease: if for the first year the child has to add about 6 kilograms, then for the second – only two and a half, and for the third – around two. A weight deviation in 6-7% according to such tables – it is normal, in other cases it is possible to speak about underweight or overweight: up to 20% the easy form, higher than 20% is necessary correction of food. Sharp change of rates of addition of weight can speak about emergence of problems with health.
