My baby has colic I need some soothing ideas?

my son had colic and acid reflux, and was just like ur daughter. screaming while eating has a lot to do with acid reflux, and late at night can be from the milk coming back up and causing pain. try the zantac and see if it helps any. it wont hurt her. also, a swing did wonders to calm him down, maybe it will help her as well.
