When he came home from school that day, I asked him if he smiled big for his pictures. He said, "No, I put my lips together like this." and then pressed his lips together to show me. Figured the pics would be cute regardless. I was right.
I love the first one, where it looks like he's on the verge of tears. If I have a camera in my hand, he INSISTS I take a hundred pictures. But I guess if it's a stranger, he's a little more wary.
