Hello everyone! Can you tell me who gives the baby D3 and in what dosage? The pediatrician said 1000 mcg is needed daily, I bought Baby Detrimax, in one drop here it's 200 mcg, so we need to give the child 5 drops, but the instructions say for babies born up to 1 drop per day. How should I proceed and how much should I give in the end? And moms, who give Baby Detrimax, is there any side effects with the children?
