Miles has really taken an interest in puzzles lately, and not just to chew on the wooden pieces. He can match up the pieces and he tries really hard to get them to align perfectly to fit in their spot. And when he's concentrating on something like that, he sticks out his tongue to the corner of his mouth. It's pretty cute. And when he sees either Mitch or myself work the puzzle, he claps his hands for us, as if to say "good job! you did it!"
