What has 4 legs and a great smile?

A crawling little fella!!!
Okay, so they aren't legs but he's getting around.
I was out of the country when I got the email from his mom letting me know that he started crawling. I had really hoped I could have been there for the very beginning but I'm glad to see it now.

He's much like his brother, just a second shy on the actual smile for the actual picture.
Or... it could be the photographer. :)
