Running

Ummm, so you'll have to crane your neck a bit, but here's a video of Nathan running!  He just moves his legs with so much momentum that you have to think that he's going to shoot out of his chair and start running!  We noticed him doing this in his carseat and then when you put him in his chair. 

Previous to this, he was talking and carrying on, but of course, when I started recording, he just sat there quietly.  (Afterwards, I found out that he was working on a doosy of a diaper and it leaked into the chair!)
