This might be a silly question but I actually need some advice on it.... So my daughter is on Enfamil AR and we ran out of formula last night well the only store that was open was Walmart they didn't have any Enfamil AR and they didn't have the Walmart brand of the added rice starch exclude just like they are some other half got the Walmart brand of the Gentlease basically do you think it'll be okay to give her that or should I run to the store and get something else I've done some research and it says it's fine to switch baby back and forth and he got the gentle one because he didn't want to have her get a bellyache from the regular formula do you think it's okay to continue giving her the Gentlease one until it's gone or should I run back to the store and get the other one she was only put on AR because when she was very little she was spitting up alot but it's been getting better I've done my research in the only different thing is AR thicker for the babies that spit up more
