Yeah, I think he's petty cute, too, but I'm totally biased.
If you can believe it, he was actually pretty upset for most of that photo shoot. He was in a strange place with unfamiliar people, and he was really scared.
Nemo is his first character obsession. A couple of weeks ago, he went to his cousin's house, where they watched a little bit of Finding Nemo. And since then, he's been asking to watch it constantly. Unlucky for us, we have owned Finding Nemo for several years (long before Seth was born), so we relented. Now he's a Nemo addict. :)
