My daughter is on similiac isomil because she was having really bad gas on the similiac advanced she seems to get really bad gas still at a certain time in the evening is the normal or should I look into changing her formula again?
Maybe try Enfamil. I know people say, "they're the same thing," but when I had my some on Similac, he was very gassy so I switched to Enfamil and he stopped getting so gassy. Unlike Similac, Enfamil is more powdery and dissolves easier, while Similac is clumpy and doesn't dissolve so easily. Not sure if that has anything to do with it, but my son did much better on Enfamil.
I would try the dr browns THEY ARE AMAZING!! also there is the similac called sensitivity RS, my daughter had a lot of issues with gas and spit up etc, when she switched to that it worked wonders. She is four months old and sleeps all night without gas pains waking her up like they used to
