Question
Do newborns absolutely need to digest cod liver oil?
Answer
Generally speaking, if newborns lack sunlight exposure or are bottle-fed, they should start supplementing vitamin D from one month of age until they are 2 to 3 years old. This is to prevent vitamin D deficiency. At around 3 months old, infants typically need to supplement with A and D calcium, and it is recommended to take them on an empty stomach. Additionally, mothers can take calcium-based medications and vitamin D supplements to increase the calcium content in breast milk, so the infants do not need extra calcium supplementation.
