Spit up/ throw up

Idk what to do anymore my baby has spit up/thrown up after every feed since he was born. We’ve switched pediatrician twice and they’ve both had said he’s fine because he’s gaining weight and also he’s a happy spitter. (We’ve changed similac a few times but nothing changed) It’s pretty annoying cleaning it up but I’ve gotten used to it but it’s even more annoying going out in public and having friends or non close family ask why he does this and that and how it’s not normal 😒 anyways I asked about when he eats food she said it would prob get better since food is thicker but I gave him a new yogurt today that was pretty thick and he still threw it up now my house smells like cheese 🤦🏽‍♀️ I’m also concerned about when he drinks reg milk will he throw that up too? I just don’t know what to do I feel like all this spitting up after his bottle isn’t normal but I don’t know what to do! 😣😣
