V.-- my second son was a tummy sleeper. Even when he was very little, he would turn sideways in his infant carrier and swing, trying to turn onto his tummy. People would always say to me, "Do you know your baby is twisted in his seat?" But every time I straightened him out, he would instantly turn sideways again. Then, as soon as he could roll over, he instantly rolled onto his tummy in the bassinet and crib. I would pick him up and lay him down again on his back, and he would instantly roll onto his tummy again. I was really worried about SIDS,so I asked my pediatrician what to do, and he said, "You could set your alarm for every hour and keep flipping him over, but he'll probably just keep rolling onto his tummy." So I bought him those breathable bumpers (have you seen them? They're kind of a padded mesh material. I got them at Babies R Us-- here's the link:

My doctor said that once they can lift their heads, there's much less danger of suffocation, anyway. My son was bound and determined to sleep on his tummy; he would just keep rolling over no matter how many times I flipped him. I was so scared at first, but he was fine. My good friend later told me that she let both of her kids sleep on their tummies because they slept so much better that way and actually slept through the night. She also told me that she had some kind of baby monitor that would beep if the baby was completely motionless for 20 seconds. I looked online (babiesrus.com) and I guess you put a sensor under the mattress which detects motion and alerts you if your baby becomes motionless. I do remember my friend saying that sometimes it gave her a false alarm and scared her to death for no reason, and the product info online says that sometimes, if your baby is in a very deep sleep, his breathing may not be detected. But the product reviews seemed mostly positive-- I think they gave it 4 1/2 stars. I didn't know about these monitors when my son was going through this (maybe because we had such a tiny house that we didn't need a monitor, so I never checked into them), but if I had, I think I would have invested in one for my peace of mind. If you do get it, though, I'd save the receipt just in case it starts giving you a bunch of false alarms and waking you up needlessly all night. And by the way, my son is now 15 months old and still sleeping on his tummy. I still lay him on his back at naptime and at night, and he still instantly rolls onto his tummy. It was a battle I just couldn't win, and he ended up being fine. Maybe look into getting one of those monitors if it'll keep you from worrying?

By the way, my mom made fun of me for worrying so much because she said all four of her kids slept on their tummies because that was what doctors recommended then, so babies couldn't choke if they spit up. :) Oh well-- we just try to do what we're told, right? But my baby seemed to know what was best for him. I'm the same way-- I absolutely can't fall asleep unless I'm curled up on my side, so I can imagine his frustration when I kept flipping him over! :) Sorry this is so long. Good luck!!
