Here are some pictures of Naomi playing around on an exercise mat. It definitely seems to be an easier (and softer, ie better) surface for her to move around on than the previous rug+2blankets situation. In one of these pictures, Naomi is pushing herself forward to try to reach a couple of toys, but then ends up rolling over instead. I don't think that was her intention. Today we went to the park for half an hour or so, and she rode in the baby swing, and liked it. It's so fun that she's getting so old...
