Growth and development is an important feature that distinguishes children from adults. Growth refers to the growth of various organs and systems of children's bodies, and there can be corresponding measured values to express the changes in their quantity. .
The commonly used indicators for monitoring growth and development are weight, height and head circumference.
1. Weight: It is the most important and sensitive indicator to reflect children's growth and development, and it indicates children's nutritional status, especially in the near future. Weight gain is the fastest at the age of 0 ~ 3 months, generally reaching 600 ~ 1000 g, at least not less than 600g, at the age of 3 ~ 6 months, 600 ~ 800 g, at the age of 6 ~ 12 months, with an average of 300g 1 year, and the growth rate will obviously decrease.
2. Height: it is the basis for correctly evaluating the physical development characteristics and evaluating the growth rate, reflecting the long-term nutritional status. Height is also the fastest growth in the first year after the baby is born, with an average growth of 25cm in the first year, 1 ICM in the second year, 4-7.5 cm in the third year, and 4-6 cm annually thereafter.
3. Head circumference: an important indicator of children's brain development and skull development. The average head circumference at birth is 34 cm. It grows fastest in the first year after birth, with an average head circumference of 46cm at 1 year, and an increase of 2cm in the second year.
Parents should pay attention to the baby's indicators in time, and seek medical advice in time if the indicators are abnormal.
