Children’s height is an important indicator of parents’ concern about children’s health, children’s growth and development of the law, the younger the age of the month, the faster the growth and development. The height standards are as follows: 1, the height of newborns at birth is generally 48-52cm, most children are about 50cm, there is a fluctuation range of 2cm; 2, the first year of life, the fastest growth in length, about 25cm. 3 months before the length of the growth of about 11-13cm, equal to the growth value of the next 9 months, 6 months when about 15cm, to the age of 1 year old, length of about 75cm; 3, the second year of height growth gradually slowed down, the younger the month, the faster the growth. The length of the body is about 75cm; 3, the second year of the height growth rate gradually slowed down, about 10-12cm, that is, about 87cm at the age of 2. After the age of 2, the height growth is less than 5cm per year, and the growth rate is on a downward trend; 4, the standardized formula for the height of the 2-6 year olds is age × 7 + 75 (cm), and the formula for the height of the 7-10 year olds is age × 6 + 80 (cm). If the growth and development process can not reach the above standards, parents need to pay attention to it and seek medical attention to identify the causes and clarify whether there is a growth disorder disease. Usually, if a boy’s height is less than 71.2cm at the age of 1 week and 81.6cm at the age of 2 weeks, and if a girl’s height is less than 69.7cm at the age of 1 week and 80.5cm at the age of 2 weeks, this is consistent with the diagnosis of dwarfism, and it is recommended that the child be actively treated accordingly.
