Last night I put Molly down on Uncle Kyle's floor for some belly time and she was not happy about it. Next thing we knew she had rolled over from her tummy to her back. No warning. No work up. She simply was on her stomach one second and then on her back the next. A definite blink and you'd miss it move. Of course now we're trying to get her to do it again and I think we're pissing her off with all the tummy time. Heh.
