Ben's newest tricks

About a week ago, my little 6 month old learned how to pull himself up to stand and has also figured out how to move himself from crawling into a sitting position.  However, since he doesn't really get the "if I let go of the chair I will crash to the ground" thing yet, we have seen and heard quite a few bumped heads.  Still, I can't help but smile every time I turn around to see him standing up with that big proud grin on his face.
