Weird question!!

Can some of you ladies post a pic if you have any of the amount your baby spits up after feedings?

My boy spits up/vomits a lot or what I think is a lot. He is already on nutrimigen formula, we burp every oz to 2 oz and we hold him upright for at least 30 mins after every feed. He doesn’t seem to be in pain after he eats or when he spits up, it just seems like a crazy amount of spit up to me, so I’m wanting to compare his spit up amount with other babies around his age. I know it’s a strange request but I’m a FTM and I’m not sure what to do, I’m afraid to add rice or try different formulas if he doesn’t truly have acid reflux. I spoke to his dr at his 1 month check up and he didn’t seem concerned then so I’m not sure if if I should bring it up again at his two month check up next week.
