Question
How long should babies take vitamin D supplements?
Answer
Babies require a daily vitamin D supplement of 400 units from birth, usually until they are between two and a half to three years old, by which time twenty milk teeth should have grown in. This means you will need to continue buying vitamin AD drops for your child. Based on the situation you described, it seems related to weakness of constitution and the need for increased nutritional supplementation of trace elements. You can take small Schering tablets for opsonize, and a detailed hospital examination can confirm this. Symptomatic treatment is recommended.
