I had been exclusively bf'ing but we decided to give some formula at night a at the beginning of the week. Since Wednesday LO hasn't had a poo and is screaming the place down all the time unless we hold him. What on earth can I do. The neighbours have even commented that he is screaming. To make matters worse OH is away all week so I'll have to deal with it on my own. I just can't see how I'll even be able to eat. What have I done! What can I do for him? Any tips on coping???? Please help!!
