So my baby started with formula and breast milk with similac, can she change to infamil

You can use whatever formula you like, unless you get wic then you'll have to get a paper from your pediatrician to give to the wic office. @lizramos1

My sister said no cuz the babies tummy got used to similac formula and it would upset her stomach

@lizramos1, we did a different formula at first an than switched her over she did fine with the transition

I tried calling her dr but they were closed

slowly start mixing them. so if baby takes a 4 oz bottle then do 3 parts old formula 1 part new kind. Then after a few times do half and half and so on. baby will adjust
