So for the past 3 nights my son has been sleeping in his crib without being swaddled because Monday morning I woke up to him being rolled over and still fully swaddled and of course I was terrified and decided no more of that. So the first night I was worried that he wasn't going to sleep because he's been so used to being swaddled and it was a complete opposite he slept right through the night with no issues.

Now my problem is he sleeps on his stomach. As soon as I put him in his crib for bedtime and I turn the monitor on he's already rolled over on his stomach. And I know I'm going to hear " back is best" but I can't force him back over because he's just going to roll over again. I even stayed up the first night watching him sleep with no problems because I was scared of him sleeping on his stomach. But now the problem is he rolls over to the edge of the crib and he got his arm out and he couldn't get it back out so it was stuck. Everyone says bumpers are a Suffocation hazard so what should I do to keep him from getting his arm caught?
