Letting Infant Sleep on Tummy
I know that because of SIDS the AAP and other organizations/doctors recommend almost always putting your baby to sleep on their back, except in extreme cases of reflux or other medical problems. With my first daughter, I always put her to sleep on her back, but she learned to roll over to her tummy at about 7 or 8 weeks, and slept much better once she did. With my 7 week old, she has not learned to roll over and does not seem like she's planning to try it anytime soon (like my first did), but I have let her sleep on her stomach a few times...
