Rocking, Not Rolling

This morning Claire is doing a lot of rolling onto her side. She goes to her right side, gets a little frightened and then rolls back to her tummy.
For the most part it seems controlled. Every time I tried to get a picture she rolled back over to her tummy. Basically, I know she Can do it, she would just rather Not do it.

Amendment:
She was spitting up a ton so I decided tummy time was over. I rolled her a little to her side then used her toys over and around her head to entice her to finish rolling. And it worked!
