I took a lot of pictures of Sofia yesterday and most of them came out blurred and horrible, but I like this one a lot. It was the picture I almost didn't take—she was finished smiling and posing cutely—but I liked her look of concentration and the fact that she sits, surrounded by her toys and books, absorbed in a small cardboard box that checks came in. I watched her figure out how it opens and closes. I watched her put her yellow block inside and carry it through the house. She played with it for nearly an hour, finally discarding it as she crawled into my lap, ready for a nap.
