Nothing like having to spend an entire day with your baby as he screams in pain because the formula you are trying out isn't agreeing with him all of the sudden. Well that was how my Sunday went, it took me 2 bottles to figure that out and by that point he was hurting and I could do nothing to comfort him. Luckily I had a can of something else in the pantry that seemed to make him a much happier baby but this whole trial and error thing sucks, I just want to find one that works well for him
I miss breastfeeding, this blows!
