I think I am crawling??

So Braydon has been learning a lot of new stuff lately.  He is starting to sit up on his own (about 30 seconds is the longest), he holds his bottle all by himself every time he eats, he learned how to make bubbles learned how to scream and we think he is crawling.  He is doing what the books call a "bear" crawl.  He pretty much gets up on his feet and then rubs his forehead on the ground.  The video will show it a little bit, but he pushes himself around the living room in a circle.  It is even more challenging when Wrigley keeps in his way!
