The first time: from birth to one year old
1 year of birth, most children are about 25cm in length. The length of 0~3 months is 3cm, 4~6 months is 2cm, and 6~ 12 months is 1.0~ 1.5cm, so it is best to measure the height of children under the age of 1 every three months.
Second time: 1 to 2 years old
In the second year, the baby will grow about 10~ 12cm. It is recommended to measure the height from March to June every year.
The third time: 3 years old to adolescence
From the third grade to adolescence, it is 5~8cm long every year, and it is best to measure the height once every six months.
When the child reaches puberty, the boy is 8~ 12cm long, the girl is 6~8cm long and the girl is 25cm long. Due to the accelerated growth, the height should be measured once every six months.
Extended data
Parental inheritance affects height by 60%~70%. The child's height is close to the upper or lower genetic limit, and the deviation can reach 4~8 cm. And this 4~8 cm can be said to be a world of difference for a person's adult height. Compared with genetic factors, acquired scientific intervention has 30%~40% influence on height, so don't think that intervention is useless.
Genetic height calculation formula:
The boy's final adult height (cm) = (father's height+mother's height+13)/2 5 (cm)
Girl's final adult height (cm) = (father height+mother height-13)/2 5 (cm)
