Spitting up every feed

Connie

My son is now 7 weeks old. I have him in Enfamil gentle. But he spits up alot after every feed.

He didn't latch to bf. So I pumped but didn't get much out. And would supplement with both breast milk and reg formula. But he spit up alot. And we switch to gentler at first seem to help no as much spit up. But the past week he has increased.

I don't know what to do.
