1, adjust the diet: eat more foods rich in calcium from the diet. For example, a baby of 10 month can already eat eggs. If you are not allergic to egg white, steam the egg custard for your baby every day, or add chopped shrimp skin to the egg custard. Shrimp skin is also rich in calcium. In addition, it should be noted that although we have started to add two kinds of complementary foods, we still need to drink more milk, because milk is also rich in calcium, and we usually drink 600-700ml of milk a day;
2, vitamin D supplementation: pay attention to vitamin D supplementation, generally 400-500IU per day, if you have started to supplement, you should also pay attention to more sun exposure, because sun exposure can synthesize natural vitamin D through the skin, and vitamin D can promote the absorption of calcium;
3, calcium supplementation: If the child has taken calcium in the diet, but the effect is not obvious, calcium can also be supplemented if necessary.
