The Butt Scootch....and trying to roll over

Here's a video of Kelsey scootchin a little bit. (Everytime I turned the camera on she would basically stop and only move a bit) She lifts her little toosh off the ground to scoot herself :-) One minute she will be on her mat, then I'll turn back to look at her and she is off the mat.

Now that I put her on the ground more she is showing signs of wanting to try to roll over. Here's a video of me trying to get her to roll.
