Back to sleep?

OK, I don't know what happened, but this morning I woke up to see Jordan sleeping on her tummy! She slept on her tummy at around 6 weeks for a few weeks, but then really preferred her back. I have noticed in the last couple of weeks that she rolls over on her side when I lay her down. Kenneth said that around 1 am she was rustling and when he checked the monitor she was on her belly! It's just crazy because rolling over from her back to her belly is not her favorite thing to do, so I'm just so surprised that she did it in her sleep! But, I'll take it because she slept for 12 hours and woke up happy! Yay!
