He's a happy little boy, who is very little trouble (except that he gets into everything, though he's not actually being "naughty"), but he doesn't often break into a big smile, and will sometimes fix you with a solemn little face like this one (I think he's also wondering why people try to talk to him with big black things, i.e. cameras, in front of their face). His Christmas t-shirt, ordered online, was way too big for him, so looks a bit shabby, but still cute.
In the park near my other sister's house on Christmas day. He went up and down this slippery dip innumerable times. Strange how children love so much repetition.
