Finally!

Heather caught the roll on video. We're still tyring to get a better one, but this one should work for now.

Another Not Rolling Over Video

Here's another one showing pretty much the same thing. Heather swore that she could do it.
I've seen it since then, but Avery's a little camera shy.

Rolling Over

After sorting through what seems like countless videos of Avery laying on her tummy and going through the same process:
1. Kick around, maybe rock to one side but not over
2. Stop kicking
3. Bury face in the mat and cry
I found a good one.

Concentration

This is Avery trying very hard to concentrate on an elephant toy. Also notice the improvement in her hand-eye coordination.
