my son is 5 months old and I want to know the dose of Vitamin d3 cholecalciferol drops. please suggest about 400 iu or 800iu

A. See the initial age for six months it’s going to be five drops only which you can give to the child one time and if it is meant to be given twice then your doctor would recommend you on that so in case of doubt if it has been recommended by the doctor please crosscheck with your doctor only
