/kloc-What is the standard value of the baby's weight and height for 0/9 months?

19-month-old boys have a standard height of 83.2 cm and a standard weight of 1 1. 1 kg. The standard height of a female baby is 8 1.7 cm, and the standard weight is10.4kg.. For Xiaobaobao, the weight gain in the first half of the year will be relatively fast, so for the first half of the year, the birth weight plus the month age can be multiplied by 0.6 to calculate the weight, while for the second half of the year, the growth will be relatively slow.

Extended data

Baby's weight gain law:

Normal full-term babies weigh about 2.2kg-4.3kg at birth.

The baby's weight increased by 0. 18kg-0.2kg per week in the first three months, by 0. 15kg-0. 18kg per week in the fourth to sixth months, and by 0.09kg-0. 12kg per week in the sixth to ninth months.

According to the multiple of weight gain, the baby's weight at 6 months is twice that at birth, about 3 times at 1 year, about 4 times at 2 years old and 4.6 times at 3 years old.

In the second year after birth, the baby's weight increased by an average of 2.5kg-3kg.

After 2 years old, the average annual growth rate is about 2kg, until puberty.

Weight calculation formula:

Weight within 6 months = birth weight+month age × 0.6kg.

7- 12 month-old weight (kg)= birth weight+month-old × 0.5kg

2-7 years old weight (kg)= age ×2+8kg

Height is the sum of the length of fingers, trunk and lower limbs. At different stages of the baby, the proportion of the three is different.

The younger you are, the greater the ratio of head to upper body. As you get older, the lower body will grow faster than the upper body.

The average length of a baby at birth is about 50 cm.

1 year has the fastest growth, with the average monthly height increasing by 2.5cm in 1-June, by 1.5cm in July/February, and by about 25cm in1year, which is higher than that at birth 1.5.

In the second year after birth, the growth rate of baby's body length began to slow down, and the annual growth rate was only 10- 12 cm.

From 2 years old to adolescence, the baby's body length increases by 6-7cm on average every year.
