There is no absolute value prescribed for how tall a baby grows in a year between the ages of 2 and 3. Usually, the average height growth value is about 7cm~10cm. The height of different babies will be affected by genetic factors, gender, daily life and dietary habits and other aspects. Normally, the average height increase is about 7cm~10cm. Babies whose parents are both taller will have a slightly higher height growth; male babies in the same age group will grow faster than female babies; and if babies have good dietary habits, balanced nutrition, and do a moderate amount of activity, their height growth may also have a certain degree of advantage. So 2 years old to 3 years old this year’s height growth value, can not be generalized, as long as the growth value in the normal range can, parents do not need to worry too much. Daily attention should be paid to the balance of the baby’s nutrition, eat more protein-rich, vitamin-rich foods, such as milk, eggs, carrots, bananas and so on. Lead the baby to moderate exercise, go outdoors to sunbathe, etc., in order to promote the baby’s growth and development, help grow taller.
