Formula for spit up?

Kayley

I currently use Similac sensitive which helps a lot with his gas and sensitive tummy but he spits up a LOT after almost every feed and then has been spitting up curdled milk an hour or so after eating. Curious if I should try a different formula? I’ve tried total comfort but it made him even worse and wouldn’t keep it down. He doesn’t have a milk allergy.

Thank you!!
