Under normal circumstances, the baby doesn't need to eat cod liver oil after 2 years old. Give the baby cod liver oil mainly to supplement calcium, promote the baby's growth and development, and prevent the baby from suffering from rickets due to calcium deficiency. Children under two years old grow fast and need a lot of nutrition. Because this period is an important period for children's bone development, if the calcium content is insufficient, the baby's bone development will be affected, and in severe cases, it will suffer from rickets. After two years old, the baby's bones have been basically shaped, and it is meaningless to use cod liver oil to prevent rickets again.

Cod liver oil can generally be eaten after the baby is born 15 days, and should be eaten less at first, and can be taken according to the doctor's advice. If the baby's stool is normal and gradually increases after one week, the baby can eat until he is 2 years old without diarrhea.

In winter, the sunshine is short, so give the baby cod liver oil. Avoid eating cod liver oil with milk powder, which will affect the absorption of nutrients. After eating cod liver oil, you should get some sunshine. Be careful not to sunbathe through the glass. Sunbathing is more beneficial to the skin's absorption ability. If the baby has signs of calcium deficiency, you can still eat cod liver oil every day. When the weather is fine in summer, you can appropriately reduce the use of cod liver oil for your baby.

Pay attention to the timing when taking cod liver oil. In order to have better absorption effect, you can eat cod liver oil after drinking milk in the morning. In addition, you need to bask in the sun after taking cod liver oil. The absorption effect of cod liver oil will be better after sunlight exposure.
