From prenatal to pregnancy to birth, the child actually experienced a lot of problems to be able to be born healthy. When born, the general normal growth and development will be carried out from the individual, the normal growth and development of the time, in the newborn period, generally speaking 2.5-3 kg for the normal growth and development of the standard, when gradually grow up 1 year old, the child’s average height will grow to 75cm, weight will grow to about 10.5 kg. When 2-3 years old, growth and development will decline, not as fast as before the age of 1, generally will grow 4-5 pounds, when 3 years old after the growth and development will further slow down. But there is a formula to remind parents to make a simple determination of height and weight, that is, age x 2 + 8, is a different weight indicator for each age group, so you can take this formula to compare, but there will eventually be children who grow particularly well, there are also children who are relatively poor. If your child is not growing well, you should talk to your pediatrician or pediatrician to find out the reason for this, so that the growth can be kept up. If the growth is particularly fast and beyond the normal standard, it is still necessary to control appropriately, not that the fatter the better, childhood obesity is also a common problem in recent years.
