The roll that wasn't

Yesterday I put Collin on the yoga mat and he rolled to his back. So this morning I decided not only would he roll again, I would catch it frame-by-frame on my camera. Here's the result:

In position -
Shifting my weight on my right side -
Taking a break to eat my hands -
Hmm, I think I may be getting stuck -
Uh oh, I don't appear to be making any progress.
Okay guys, this isn't funny. Put the camera down and get me off my side!
Thankfully Dad came to the rescue.
