So I started off with simillac formula and my baby was being very gassy and pooped once in a while so they said he was allergic to the cow protein and switch him to nutramigen. He has been on nutramigen for about 2 weeks now and it seems like one day he is okay and the next he is just so uncomfortable and gassy and just plane out unhappy 24/7 idk what to do anymore. On top of that he has silent reflux and does more than just a spit ups almost everytime he feeds! I've tried feeding him upright and keeping him like that at least an hour before I lay him back down in his car seat. he can't sleep flat in his back because of the silent reflux. Has anyone or is anyone in nutramigen and having problems with it? or is this just normal?
