First, strengthen nutrition for children, and eat more foods rich in high-quality protein, such as milk, eggs, pork, beef and other lean meat.

Second, give children more calcium-rich foods, such as milk, eggs, sparerib soup, shrimp skin, seafood and so on.

Third, let children have enough sleep, because the growth hormone that promotes growth is mainly secreted at night, so sleep is also very important.

Fourth, let children participate in sports activities, especially skipping sports activities, such as playing basketball, badminton and skipping rope.
