Weight gain standard for female babies

There are certain growth standards for children's height and weight, because height and weight reflect the child's physical development status to a certain extent, and meals should be arranged reasonably. Some children grow slowly and their body's absorption capacity is not particularly strong, so they develop slowly, resulting in their height not being particularly tall. Some children develop early and grow particularly tall as they grow. Let us take a look at the standard height and weight table for babies.

Based on the results of the children's physical development survey, the Department of Women and Social Affairs of the Ministry of Health organized relevant experts to research and formulate the "Reference Standards for Growth and Development of Children Under 7 Years Old in China", which was officially announced by the Ministry of Health on June 2, 2009. Boys and girls develop differently. Parents can refer to the data in the following table to see if their child's height and weight are normal. It should be noted that the following data are not absolute standards. As long as the child's height and weight are within the normal range and there are no abnormal symptoms, parents do not need to worry too much.

Height and weight standard for baby girls

Body length refers to the sum of the lengths of the head, torso and lower limbs. The proportions of the three are different in different stages of the baby. The average baby's length at birth is about 50 cm. The fastest growth in height is in the first year, with an average increase of 2.5 cm per month from 1-6 months, and an average increase of 1.5 cm per month from 7-12 months. At one year old, the height is 25 cm higher than at birth, which is about 1.5 times the height at birth.

In the second year after birth, the baby's height growth rate begins to slow down, only increasing by 10-12 cm throughout the year. From the age of 2 until before puberty, a baby's height increases by an average of 6-7 cm each year. The younger you are, the larger the ratio of your head to your upper body. As you age, your lower body grows faster than your upper body. The formula for calculating the height of babies aged 2-7 years old = age × 5 + 75 cm.

Methods for predicting adult height

1. Male height = height at birth (cm) ÷ 0.2949; Female height = height at birth (cm) ÷ 0.3109. Please note when using this formula: it is only applicable to normal full-term newborns; if the height data can be measured with an accuracy of 0.1 cm, the height prediction will be more accurate.

2. Male height = height at 3 years old × 0.545 + parents' average height × 0.544 + 37.69 (cm); Female height = height at 3 years old × 0.545 + parents' average height × 0.544 + 25.63 (cm), standard human height prediction formula (genetic law).

Finally, I would like to remind all parents that when measuring your baby's height, you should take off his shoes and hat, so that the result will be more accurate. In addition, babies under 3 years old can be measured while lying flat. When measuring, make sure your knees are straight and someone has their head fixed with hands.
