My tiny ds is feeding great and falls asleep on boob. I sit him up, sometimes getting wind up and keep him upright on my chest for a while. He's out for the count. And then I put him down and he wriggles and grimaces with trapped wind and all that will settle him, even if I get wind up, is to feed again. .and the cycle continues!
Funny enough if I side feed him he will go off to sleep there and doesn't seem to suffer at all.
