So my baby and I are upset . For the first 2 months my baby was on similac pro advance . He did so well . No allergies, barely any spitting up , and very content after bottles . Last month I got approved for wic. They told me they can’t offer the pro so I had to change him to similac advance . He’s been on it for 3 weeks . He gets about 6 bottles a day and he spits up at least half the bottle after every feeding . I have tried feeding him half, then burp and let him sit for 30-60 mins then finish . And he is still spitting up non stop . He’s crying more often and really fussy . So I am convinced that formula is not doing it for him. Today I went and bought the regular sensitive formula since wic also offers that. And he’s srill spitting up but slightly less than before .
