The violent prolongation of small babies refers to the period of time when the baby grows and develops the fastest in terms of physical and physiological functions. The long period of small babies should be within the time period of one year, which is the period of the most rapid physical growth and physical function development of small babies.
The fierce long-term growth of small babies is characterized by the obvious "growth" and "development"
In the process of growth and development, "growth" is used to indicate the growth and height of children in the body, and "development" represents the maturity and perfection of children's physical functions. Children's physical growth, such as weight, length, head circumference changes, and physiological function development and maturity, etc., in the process of growth and development, are carried out in accordance with certain developmental laws.
From the fetal period to the adolescence, the physical and physical function growth and development change dramatically. Childhood is an important stage in the development of physical and intellectual abilities
Physically speaking,
The growth changes of small babies are roughly marked by changes in head circumference, weight, and body length.
1. Weight: In the first three months after the birth of a small baby, the rate of weight gain is very rapid. Increase by about 200 to 180 grams per week, and then slow down slightly. In the three months from the fourth to the sixth month of life, the average weekly weight gain is about 180 to 150 grams. That is, the rate of weight gain in the first half of life is faster, and the rate of weight gain after that is slower than before.
2. Length: The fastest increase in the first 6 months after birth, with an average increase of about 2.5 cm per month. From 7 to 12 months after birth, the average monthly growth is about 1.2 centimeters. The length at the age of one year is about one and a half times longer than when it was first born.
3. Head circumference: The average head circumference of newborns at birth is 34 cm, and the fastest period of head development is within the first 6 months of birth. The head circumference increases by about 8 cm compared to that of birth, which is similar to the growth rate of body weight and body length. The head circumference grows by about 3 cm at 6 to 12 months of age. The average weight of the brain, which is about 350 grams at birth, has exceeded about twice the weight of birth by 9 months after birth.
In terms of the function of the body:
With long-term changes, the little guy's development indicators from rest to movement, asana, language, emotional expression and other aspects have been significantly improved and improved
In infancy, athleticism, intelligence and language skills are all rapidly evolving. By the age of about one year, most of the babies have completed the activities of physical movement and behavior change from rest to movement, and have the ability to walk from recumbent position, sitting position to standing position. Most of the language ability can also be achieved, will express appeals and wishes, and there are different developmental manifestations of intelligence such as individual cognition and emotion. The gradual improvement and maturity of various functions in the independent walking, speaking, emotional expression and intelligence of human beings. The growth and development of children are extremely closely related to the environmental conditions, climate, geography, nutrition, diseases and other aspects of growth. Although genetic factors have a certain impact on children's growth and development, children's acquired growth environment factors play an extremely important role in promoting the good development of their growth and development.
