Babies usually eat cod liver oil until they are two years old. The main function of cod liver oil is to supplement vitamin D. Vitamin D should be supplemented two weeks after the baby is born, 400U per day, and increased to 600U per day after one year old. Adequate cod liver oil can be beneficial to calcium and phosphorus absorption, metabolism and bone calcification. If the amount of cod liver oil is insufficient, it will lead to signs of rickets in children, such as restless sleep, irritability, crying and sweating at night. If the baby has signs of rickets, it can also be manifested as a square skull, chicken breast, beaded ribs, bracelets, anklets, O-legs, X-legs and so on. Therefore, it is necessary to observe these symptoms of the baby and increase the amount of cod liver oil if necessary, but not too much to prevent poisoning. Babies should get more sunshine and take part in sports, which can promote the synthesis of vitamin D and promote the metabolism of calcium and phosphorus, so babies can eat fish.

Theoretically, it is not easy to be deficient except for premature infants, children in underdeveloped areas and pregnant women, but chronic diarrhea may cause vitamin A loss, leading to symptoms such as dry eye and night blindness. Vitamin D helps to promote the absorption of calcium and phosphorus, promote the development of bones and teeth, and maintain normal metabolism. Vitamin D deficiency can lead to rickets, osteomalacia and so on.
