Am I over feeding?

I have a 6 month old who eats approximately 36-38 oz a day of formula and pumped breast milk. About 80/20 ratio. We’ve also started on solids and he eats tons of that too.

He’s in the 100th percentile, so he’s a big little dude.

I wouldn’t be concerned if it weren’t for the fact that he spits up a lot. Like, a LOT. Multiple outfit changes a day. And most of it is that gross smelling curdled stuff.
