When every baby is born, it is related to the factors in the first heaven. Some children are born with a high height and weight. Some children are born with low height and weight because of intrauterine reasons. After two and a half months, he may not reach the normal high limit. Don't worry too much at this time, mainly to see if there is a growing trend.
The first six months are the peak of baby's height and weight growth. Generally, the average height increases by 2.5cm per month, and the average weight increases by 600-700g per month. If it is within the normal range of increase, don't worry too much. If the child is not up to standard and the growth rate is obviously not up to standard, it may be necessary to discuss with health care doctors and pediatricians whether there are feeding problems or disease States. The average length of a baby at birth is about 50cm, with an average monthly increase of 2.5cm from/kloc-0 to 6 months and 1 .5 cm from 7 to 12 months. At the age of one, the height increased by 25cm, which was about 1.5 times of that at birth. In the second year after birth, the growth rate of baby's height began to slow down, and it only increased by 10~ 12cm throughout the year. From 2 years old to adolescence, the baby's height growth enters a relatively stable stage, with an average annual growth of 6~7cm. For children aged 2~ 12, the formula for calculating height is: height (cm)= (age -2) X5+85 or height (cm)= age X5+75? .
