my son is 15 days old.. when I give my breast feeding milk he has loose motions... but when we give formula milk he's okay and good...plz suggest

A. Loose motions are common in their age but this is surprising that your child is not having motion with the formula I think it would be good for you to get examined by the doctor sometimes kids are lactose intolerant with the mother but you have to check with your doctor for better clarity on this
