Actually I think it was just that her head was too heavy to hold her up when she rolled to her side - I wasn't watching. I put her on her tummy when Nick left this morning and I sat on the couch and I was reading something and I looked over at her because she just seemed quiet and she was on her back - I don't know how she did it and she won't do it again - so I think it was a fluke - but I was excited - I called Nick - he'd only been in the car 5minutes - outside Blockbuster in fact.
