So, that is why this video is such a big deal. I got her to perform. On camera. With Samantha as a "translator". She has a few more signs she can do, but I decided not to push my luck! It was so hard not to squeal with excitement and call Jeremy over (which would have shut down the performance instantly).
So here you have it:
Bird (that was the first time she'd done it!)
Baby (I swear she can do it and does it so well)
