sleep rolling?

I've heard of sleep walking and even sleep talking but last night Morgan decided to sleep roll. We put her down for bed last night on her back like we always do and at 6:30 this morning when I was marveling to myself that she had slept straight through I went into her room to get her up for the day. She was lying on her tummy. She had managed to do at night what she never could in the day, roll form back to tummy. Guess we'll see where we go from here. :)
