BREAKING NEWS: Just a few minutes ago, while I was doing some cleaning around the house, Kaitlyn was playing on her activity mat. When I walked out of the room, she was on her back. A few seconds later I walked back in and she was on her tummy! I immediately called Ron to tell him the great news then I got out the video camera. Here she is rolling from her back to her tummy, then back again all on her own.
