I feel so bad for my LO.. he just threw up so much!

I put him down for a nap and I heard him coughing so I checked our monitor (which has a camera) and I saw him throw up a ton..

I ran in there cause I always put him on his back and I was scared he was choking. But luckily he was okay.

Today I tried giving him a regular banana so maybe that was it? He’s had the gerber banana purées before and it never bothered him though.. or could be a virus.. I don’t know I just feel so bad for him😭
