My baby is 15 weeks old. He will sleep on his stomach. If he is laid on his back he wakes up almost immediately. He will occasionally turn his head from one cheek to the other while sleeping.   I've read that once babys can roll over if they end up on their stomach it's ok. He hasn't rolled over yet but the fact that he sleeps and is able to turn his face makes me feel like he's ok. Any time he's slept on his stomach he's been watched like a hawk. I feel guilty because of all the   sids guidelines but then I also feel like he's ok.  Anyone else have a similar experience?
