First of all, babies can eat cod liver oil for a long time, usually until they are about two years old. After the baby is two to three years old, the growth and development speed will obviously slow down, and the types of diet and outdoor activities will also increase obviously. Generally, cod liver oil is not needed.
Secondly, parents must pay special attention to ensure that the amount of cod liver oil that the baby eats every day is within a safe range. If you feed your baby other fortified foods or some multivitamins, you should also pay special attention to the total dose your baby takes every day to avoid poisoning caused by too much dose.
Finally, what parents need to do is to feed their baby cod liver oil according to the amount on the product manual. Generally, breast-fed babies should take cod liver oil every day, which can effectively prevent rickets caused by vitamin D deficiency. In addition, cod liver oil should be taken in the morning as much as possible, which will help the baby absorb the calcium ingested that day.
