I may have seen a couple. And heard some good toots. I've gotten some good burps too. The hiccups though... He doesn't seem too bothered by them, but they can't be comfortable.It's a lot easier once he's older. There are several methods to relieve the toots. You'll find videos of laying baby on back and in slow movement, moving legs toward abdomen helps the gas pass.
Edit: it's my understanding that a lot of things get easier when they get older. Then they become teenagers.
