What formula should I use?

Suantay • Mommy to a beautiful little princess 💕👑

I’ve tried Similac pro advanced (she spit up), pro-sensitive (she spit up little white chucks), pro total comfort (she spit up), Enfamil gentlease (she spits up). I know constantly switching isn’t good and babies are like dogs and dogs shit everywhere when you change their food... I haven’t talked with her Dr about formula options yet, I’m going to at her next appointment, but until then what is a brand and type that has worked for you?
