My daughter couldn't take gerber formula. She had to have enfamil. But we switched her to nutrigeman (not really sure how to spell it) but she does amazing with that. She has acid reflux which is why she's on that one.
@trinitysmommy, yes I'm thinking switching she spits up with all Similacs an tends to be more uncomfortable than she should be an I would love for her to be more happy lol
