There is no exact value for the baby's height and weight, as long as it is normal within a certain range. Normal full-term boys are about 45-55 cm tall and weigh about 2-4 kg, while girls are about 44-55 cm tall and weigh about 2-4 kg. The baby's height increased by about 25 cm in the first year. The formula for calculating the baby's weight is 1-6 months = birth weight+month age ×0.6 (kg), and 7- 12 months = birth weight+month age ×0.5 (kg).
Cause analysis: the baby's height and weight are related to many aspects, and the feeding method and the absorption and utilization of the body's own nutrition also vary from person to person.
Suggestion: Insist on breast-feeding, better improve the baby's immunity and nutrition absorption, and add complementary food for 6 months to provide the baby with sufficient nutritional diversity, protein, calcium, phosphorus and other minerals. Make a good and regular schedule.

2, 5-6 months baby: the baby should control the amount of milk during artificial feeding. If he is allowed to eat, the baby will grow too fat. Generally speaking, the baby's milk quantity in a day should not exceed 1000 ml.
3, 6-7 months baby: 6-7 months baby can add milk instead of food, at this time the baby's milk is still mainly milk, about 700 ml per day.
