He Crawls, He Sits, and he's pulling himself up!

This boy is growing way too fast!!! I can't believe that he's already pulling himself into a standing position. It's so sad that he's not such a baby anymore! It's so strange because he's still such a little guy--he doesn't look old enough to do everything that he does. He has his 9 month appointment next week so we'll see how big he really is!
