Hello everyone. To those who have children with colic, did you see them fussing and looking down? How were they treated, is it necessary to treat at all, and has it passed? My daughter is 3.5 months old. Some say that up to 6 months is normal and will pass on its own, while others say that it won't pass on its own and needs to be treated, but the prescribed medication by a neurologist is being taken.
