Neonatal 7.2 kg yellow calendar

Weight: The average birth weight of newborns is 3 kg. The average monthly increase in the first half of life is 600 ~ 800g, which is the first peak of growth and development. The calculation formula can be: weight = birth weight+month age * 0.7 kg. In the second half of the year, the average monthly increase is 300 ~ 400 grams. The calculation formula can be: weight = birth weight +6 * 0. 7 kg+(month age -6)* 0. 4 kg =6+ month age * 0. 25 kilograms. At 3~5 months, the body weight is twice that at birth, three times that at 1 year and four times that at 2 years old. After 2 years old, it grows steadily to 12 years old, and the formula is weight = age *2+8kg.

Body length: 50 cm at birth, increasing by 2.5 cm every month in the first half of the year, 65,438+0.5 cm in the second half of the year, 75 cm at the age of 65,438+0, 85 cm at the age of 2, and increasing by 5-7 cm every year after the age of 2, which can be calculated according to the formula: body length = age * 7+70 cm.
