I doubt it's an issue with formula, etc. The sphincter muscle that keeps the tummy closed is immaturely developed in ALL babies... but some babies have more problems with it than others. BOth of my girls spit up everything ... breastmilk, baby food, etc. until about 8 months and then it stopped. They stayed right on their growth curves! If weight gain is normal you can assume they're keeping plenty down (even though it seems like it all comes up). Mention it to your pedi at the 4 month check, but I have a feeling doc will say not to worry... Also, my first daughter had reflux, but I learned that the spitting up and reflux are not directly related... she was on reflux meds, which made her feel better, but it didn't affect the amount of spitup. And my second daughter, who does not have reflux, spits up almost as much...
