We used this formula because it is what the hospital uses. It made my daughter extremely constipated which upset her stomach and made her fussy. Once we switched to the lower iron formula she was a much happier baby!

I want to start off by saying that every baby is different and just because it didn't work for my little man doesn't mean it can't work for someone else's.. I found this formula gave my baby extremely bad diarrhea.. Like exploding out his diaper up to his back.. Switched to a different brand and he was fine.
