My son will be six months next week and has just started rolling from back to tummy. He has rolled back a couple of times but definitely doesn't do it himself just yet. We're practicing. He does have strong neck and upper body control though.
He has just begun rolling in his sleep, he doesn't wake up, he happily sleeps that way. He's in a sleeping bag with arms free, safely in a cot. My concern is if he vomits, as he is a baby who still vomits a lot. Should I be turning him back based on this? But then if I don't wake up I can't help.
