BY Penelope Judson 2018-06-03There are usually two peak periods for human growth and development. The first stage is from birth to one year of age. The average height of newborn babies is 50 cm, and the average height of the first year of life is 75 cm. That is to say, it is 50％ The development period, starting from about 10-14 years old, is mainly affected by growth hormone, and the height growth is rapid and obvious. By the age of 18-20, the bones are closed and the growth slowly declines.6
