If you're talking about a fart, then I think you should let that baby fart all night if he/she wants to. Farting is normal. I fart, you fart, even Trump farts. We all farts, and they don't smell good. Some smell like rotten eggs, those are the worst but some smell like burt rubber. But if that baby's farting like every 5 minutes or something, then his bo0ty got a problem. He may have to see a doctor. But other than that, hope this helps! ;)
