Help baby spitting up a lot

My son is 8 weeks old and over the last few days has started to spit up a LOT. For example, last night I fed him, sitting upright, 5 ounces, which took him about 40 minutes. I burped him twice during the feeding. After he was done, he spit up 4-5 times even while I was keeping him upright.

This morning, my husband was feeding him and he spit up everywhere mid feed.

These are projectile spit ups...they are going really far! Not a little dribble! Help what is going on
