From Crawling to Sitting Up

We went to the doctor last week for Allan's 9 month check up. She asked me all the questions about whether or not Allan was doing certain things. Things like pulling himself up on thing, feeding himself, grabbing something and then putting it in the other hand. Most of those things he could do, except for go from crawling to sitting up all on his own and pulling himself up to a standing position. Low and behold, the very next day he could do both of those things! Here he is crawling and then sitting up. Now he constantly does both of those things. He's definitely on the move now!
