So I put ds to sleep on his back every night, but within minutes he is on his tummy. It is stressing me out to no end. We have a wedge in his crib because of his reflux, but if he isnt on his back should I leave it? A friend suggested getting the bebesafe mattress wrap, but I am pretty skeptical of it. I swear the kid plants his face down and is sound asleep. He knows how to roll back over, he just wont. UGH!!
