The standard formula for measuring children's weight is 2- 10 years old weight (kg) = age ×2+7 (or 8). The measurement formula of the height standard is: the length (cm) of children after 2- 12 years old = age ×7+75(cm). According to the above criteria, anyone whose height exceeds the standard 10% or falls below 10% is considered abnormal.
If the baby's growth rate is far from that of children of the same age, parents should try their best to pay attention, not too fast or too slow. If it is too fast or too slow, it is necessary to check the feeding, living environment and nutritional status in life, and make a comprehensive evaluation and correction after finding the reasons.
