What's so funny young lady?

Here lately, it's been easier to show you what's been happening with Ms. M. than tell you. Apparently, whatever I was doing last night just tickled her to death. She has an extremely hearty laugh now. I had to place the camera in such a way that she didn't know that it was focused on her. Otherwise, she gets super preoccupied with it and I can't get her to respond like I want her to.
