My little one just turned 3 months old. He has been spitting up a lot and the doctor had us try similac pro total comfort. He seemed to do okay with the formula, but was spitting up just as much if not more. He's usually on silmilac pro advance and is doing well with it minus the massive amounts of spit up.

He's a "happy" spit up baby so the doctor isn't worried about it. But he hates having wet clothes and even the "waterproof" bibs aren't saving us. So a couple days ago I decided to try one of the formulas for spit up and now he's struggling to poo. He's spitting up a little less, but is still a mess.

I'm curious if I should try mixing a scoop of his regular formula with the one for spit up (so it's half and half) and see if that at least helps with his poops?? Or is that a stupid idea? Any other formula suggestions to try? He's a mess regardless so I'm at a loss at this point...
