UPDATE FROM FORMULA: It Was No Success 😢 He Threw It Up Literally In Face Lol So Its Back To Breastfeeding I Go..
it didn't work as much as I planned he drunk most of it then wanted beastmilk
I hope it helps....most likely he drank too much too fast and that's why he threw up
you may have to just give him what he wants....and pump breastmilk to give yourself a break
