After lots of kicking and screaming...

...I got this shot. It took about 30 clicks of the camera and 15 minutes of her waving her hand in front of my lens (which is her way of saying, "Knock if off, Mama").
I didn't back off.
I kept trying, in between giving all of Sarah's animals tea and snack during our tea party.
Here's what I was waiting for and it happened in a SPLIT-SECOND!
Thank goodness for a fast camera.
