Baby boy is 6 and a half months. He was on aluminum formula due to problems with pooping. Now they gave me the similac sensitive photo on what he is on now ... hes on it for 3 days been having bad diarrhea...that gives him terrible rashes... I change him so many times and wash him to try and avoid it but it only helps a little. He woke up at 2 am today crying so bad. He had a wet fart when I tried wipping him he started screaming bloody murder. . I washed him under warm water with him crying so painfully. Any ways anyone ever had that from this fomula. Supposedly it s sensitive and better than the original one
