I'd say almost all of his wakings (be it from a nap or at night) is because he has a burp or he has to fart. Sometimes he goes right back to sleep, other times it takes forever, or he doesn't go back to sleep at all. FWIW, DS is a tummy/side sleeper. When does that stop becoming an issue?
Re: When does burping/gas become a non-issue?
I'd say that with dd it really depends on what I feed her. Like if I feed her cauliflower or broccoli, I'll give her mylicon as a pre-emptive strike before she goes to sleep because I know those are gassy foods.?
I also give it to her if I notice she's having a particularly gassy day. ?
DD is also a tummy sleeper. ?
