Second, how to eat baby cod liver oil

Cod liver oil contains vitamins A and D. Lack of vitamin A may affect the development of baby's skin and vision, and lack of vitamin D may lead to rickets, because vitamin D can promote the absorption of calcium in food and play an important role in baby's bone development. The contents of vitamins A and D in breast milk and milk are relatively small. In order to meet the needs of baby's growth and development, whether breastfeeding or artificial feeding, cod liver oil should be added from the third week after birth. At present, there are vitamin AD preparations specially made for infants in the market, which are scientifically matched and suitable for infants to absorb, but the concentrations are different. It should be given to babies in strict accordance with the instructions or doctor's advice, and it is best to choose drops. Pay special attention not to supplement too much, otherwise poisoning may occur.

In summer, the baby has more outdoor activities and long sunshine time, so the dosage of cod liver oil can be appropriately reduced. Many older babies often refuse to eat cod liver oil because they don't like its fishy smell. Mom needs to think of some ways, such as mixing it with the baby's favorite food and letting him eat unconsciously. Or prepare some snacks as a reward. Usually, you should prepare more foods rich in vitamins A and D for your baby, such as animal liver, egg yolk, shrimp skin, carrots and so on.

In winter, the sunshine is short, so you should eat cod liver oil every day. Avoid feeding cod liver oil with milk powder, otherwise it will affect absorption. If the spring is sunny, you can eat for ten days and stop for ten days. Stay in the sun for more than 20 minutes when the sun is fine. Be careful not to sunbathe through the glass. It is effective to sunbathe exposed skin. Sunlight can convert dehydrocholesterol in the baby's body into VD, which is helpful for calcium absorption. If your baby has calcium deficiency symptoms, you can still eat cod liver oil every day. It is sunny in summer, and cod liver oil can be reduced appropriately.
