Any moms have a colicky baby? My son is almost 7 weeks old and he has been an angel until this last week. He screams bloody murder for hours at a time, so I'm guessing it's colic. Someone told me that they used camomile tea and it worked great to help soothe their colicky baby. Has anyone else had this problem? If so what did you use? If you used tea how much did you give your LO?
