The main components of infant cod liver oil are vitamin A and vitamin D. It can be taken at any time of the day. It is usually recommended to take it around 10:00 am, or half an hour after your baby wakes up from his first milk, depending on the individual. In general, after 2 weeks of life, babies should take daily cod liver oil supplementation, which is needed until 2 weeks of age. Cod liver oil can effectively promote baby’s eye development and prevent vitamin D deficiency rickets due to vitamin D deficiency. Cod liver oil is an oil that is generally better absorbed in the morning. At the same time, parents need to pay attention to ensure that the baby sun exposure 1-2 times a day, 15 minutes each time, is conducive to the absorption of calcium. In addition, as the child grows and develops, the amount of cod liver oil should be dynamically adjusted, and it is recommended to review it regularly at the child health department of the hospital.
