Anyone else little one spit up a lot?

I breastfeed and my son spit up right after a lot of the time. I took him to the dr and she said since he’s gaining weight it’s not really an issue but hearing your kid choke in the middle of the night can be terrifying. Anyone deal with this or have suggestions

I have been holding him upright for 20 minutes after feeding during the day but not in the middle of the night. He also doesn’t spit up as bad during the night just every other night or a little trickledown.

Tonight it shot out his nose so I just don’t want him to keep being uncomfortable
