I know all the classic symptoms of colic and i'm quite sure she has it. Only thing i'm not sure of is when she is crying usually between 5pm and 10pm she won't feed at all. So shes going 6 hours or so with out feeding and she only has 3oz anyway. She is sleeping through the nights mostly and goes about 7 hours without a feed. Some days she might only take 10-15oz. Is this caused by colic or something else? Its so frustrating cos she seems really hungry but doesn't want to suck the teat.
