Formula

i’m a FTM and my almost 2 month old has been on Enfamil A+ but he spits up a lot, coughs/whizzes when drinking.

i’ve tried Enfamil Gentlease and Enfamil Spit up but he screams for more when normally he drinks 4 ounces but with those two, he wants to drink 4+ ounces.

he’s super colicky and unsatisfied/uncomfortable when he drinks either one of them when he’s normally a happy baby.

can anyone recommend what formula to use or what to do. im desperate!
