Formula for spit up

Right now my son uses enfamil infant but he spits up constantly and alot. His pediatrician wasnt bother by it but its alot. I bought a can of enfamil prosobee and he did pretty good on it but I only had one can. Should I use prosobee or a different formula like enfamil AR?

He started off on Similac pro-advance and did really good on it but WIC made us go on enfamil infant. If I switch to similac pro-advance would it help or could it just do the same thing?
