RE: Sleep Position Worries
We had a similar situation, although DS didn't press his face into the mattress and generally started crying during the night when he was stuck on his tummy and couldn't roll to his back. Since DS would cry, we would go and turn him onto his back. We weren't getting much sleep either. We did try the sleep positioner again and it helped somewhat, although at times, when he really rolled, he could roll right over the positioner. We had the Head 'n Back to Sleep Positioner with the tubular side supports. I don't know if it would be more difficult to roll over a wedge or not. Just hang in there and keep turning Josh onto his back or at least turning his head. It was a very happy day when DS could roll from his tummy to his back consistently. Then we didn't worry about him being on his stomach in his crib because we knew he could turn himself over. Good luck.
