Vomit and Spit Up

Hi All.... looking to see how everyone’s else baby is with vomiting and spitting up after bottles. It seems like a constant thing for our little guy. You move him after. 5 ounce bottle with a good burp and you are gonna get up chuck on ya. We’ve tried 4 different formulas, Pro Advance, Enfamil AR, Alimentum, and are now trying Soy. As a background , in January, he had surgery on his Pyloric Stenosis at 11 weeks due to vomiting Gerd and poor weight gain. So from all that maybe my husband and I are a little freaked out by every bit that comes up.
