Rolling in sleep. Send help 😭

So the past few nights my son has been rolling onto his stomach at night. He isn’t exactly a pro at rolling from stomach to back yet so he will roll on his stomach and then just cry. So we get up and roll him back and not even five minutes later, he rolls back and starts crying again. I’ve tried letting him cry it out a bit to see if he would just get comfortable but nothing. The cries go from whining to full on crying. Anyone have any advice? I was reading that using a sleep bag might help?
