Four indicators of baby growth

The baby's healthy growth is the focus of mothers' attention. Growth and development are unique physiological phenomena in infants and adolescents. According to experts, commonly used pediatric growth and development indicators include weight, height, head circumference, and chest circumference. Mothers, we can observe whether the baby is growing up from the following indicators. Moms, take a look!

1, weight

The most important and sensitive indicator that reflects the growth and development of children can reflect the nutritional status of children. The weight gain is fastest in the first 3 months of birth. It is generally a monthly increase of 600-1000 grams, preferably not less than 600 grams. 3 to 6 months of general monthly growth of 600 to 800 grams. The average increase of 300 grams per month for 6 to 12 months. After 1 year of age, the growth rate of children was significantly slowed, and the average monthly weight of children aged 1 to 3 years increased by 150 grams.

2, length

Factors affecting growth and development in the short term (nutrition, disease, etc.) have little effect on body length and are mainly affected by genetic, ethnic, and environmental factors. Body length grows fastest in the first year after birth, with an average annual increase of 25cm. The average growth in the second year is 10cm, and the average increase in the third year is 4 to 7.5cm.

3, head circumference

Head circumference is an important indicator reflecting the child's brain development. At birth, the average head circumference is 34cm; at the age of 1 year, the average length is 46cm; in the second year, it increases by 2cm, and in the third year it increases by 1 to 2cm. The average head circumference at the age of 3 is 48cm, which is similar to that of adults.

4, bust

When the child is born, the chest circumference is smaller than the head circumference. With the increase of the age, the chest gradually catches up with the head circumference. Usually when the child is 1 year old, the chest circumference is equal to the head circumference. However, due to the generally good nutritional status, many babies caught the head circumference when they were less than one year old. After the child is 1 year old, the chest growth is significantly faster than the head circumference, and the chest circumference gradually exceeds the head circumference.
