Happiest Boy on Earth?

I know we talk a lot about how happy and smiley our boy is, but Truman is seriously one of the happiest children we have ever met! He is probably in a good mood about 95% of the time. Tonight he just walked back and forth across the house laughing and smiling at whatever he saw. Specifically, he would walk into the den and either play the piano or bounce on his big ball (one of those big exercise balls) and then he'd come running back into the living room laughing and talking about his adventures. I swear, if you are ever in a bad mood just come over to our house and sweet T will cheer you up in no time :-)
