1. Growth and development indicators

Growth indicators:

Boys: weight 9.2-14.5kg, height 79.4-90.9cm, head circumference 48.2cm, chest circumference 49.4cm.

Girls: weight 8.6-14.0kg, height 77.5-89.8cm, head circumference 47.1cm, chest circumference 48.2cm.

Languages:

1) The baby's vocabulary has not only increased rapidly in quantity, but also achieved a qualitative breakthrough. They begin to master words other than nouns, such as hot, cold, dirty, afraid, walk, take, play, hit, etc.

2) Use sentences. At this age, more than 30% of babies can combine dissimilar words into a sentence.

3) Improved language comprehension ability. Babies' ability to understand language continues to improve, and those who speak early can use language to express many daily needs.

4) Recite the complete nursery rhyme.

1. Nutrition

Stature is the sum of the head, spine and lower limbs. It is an important indicator of bone growth, especially long bone growth. When the baby's nutrition cannot meet the needs of bone growth, the rate of height growth will slow down. Nutrients closely related to bone growth include vitamin D, calcium and phosphorus. Insufficient iodine and zinc can also cause babies to be short.

2. Sleep

Growth hormone secreted by the pituitary gland is an important hormone that stimulates the baby's growth. The secretion of human growth hormone is unbalanced within 24 hours a day, and its secretion is higher during sleep than when awake. Lack of sleep will affect the baby's growth. Generally, newborns require 20 hours of sleep per day and night. From 2 to 6 months, it is 15 to 18 hours; from 6 to 18 months, it is 13 to 15 hours; from 18 months to 3 years old, it is 12 to 13 hours; from 3 to 7 years old, it is 11 to 12 hours. The amount of sleep a baby needs each day varies greatly from person to person. If some babies sleep less but their spirit, mood, and growth and development are normal, there is no need to force it.

3. Exercise

Exercise can promote blood circulation, improve bone nutrition, accelerate bone growth, make bones dense, and promote height growth. Babies under 3-4 months old should lie on their stomachs several times a day to promote whole-body activities, and should develop basic abilities such as turning over, crawling, standing, and walking as they grow older. Babies should not be held or sit for too long. It is not convenient for babies to move their whole body while being held, and sitting for a long time will affect the development of their lower limbs. At the same time, after babies learn to sit, they are often unwilling to learn to roll over and crawl.
