Girls, when did their colic start (stomach hurts)? We started a week after birth. The pediatrician suggested that it might have started early because I had an injection during labor and after antibiotics (injections). The second night we can't sleep, crying... During the day they sleep well, all day. At night and in the morning I give Sab Symplex, and dill water during the day and evening.
