He started doing it again earlier today, besides he didn’t actually throw up, but it sounded like he was trying to but like swallowed it before it got out or something. And then he just did the same thing from earlier today a few minutes ago. Every time it happens, it’s usually a 5 minute episode and then he goes back to being his normal self. Could this be reverse sneezing? Please answer helpfully as we are worried at this point.
