macgrl - my dd is a tummy sleeper, and has been since she was 3 weeks old. I couldn't find another way for her to sleep at all, other than on my chest in the recliner, and that wasn't a great long term solution. I worried about it, especially at first, and my pediatrician definitely advised against it, but she's very very strong, and has always been able to lift her head so well, that I just gave in to what seemed natural for her. Because of this, though, I still am paranoid to have a lovey in the crib with her, because she's probably more likely to get tangled in something face down. She started flipping herself onto her back at 6 weeks, so that lessened my worry, too. It's proven to be not as safe, and only you can decide what's right for you guys. I just knew for myself, I felt like it was healthier for her to be getting sleep than not. Also, as soon as I made the decision, all of a sudden moms everywhere started telling me they did the same thing. My dd was a big sleep-jerker, and it seemed to help.
