"Finger driving"

I have started doing something which Mommy and Daddy both think is pretty funny. If I want their help with something, I will reach up, grab one of their thumbs, and move it to what I want help with. Sometimes I will even do this while I am being held - I'll "drive" Daddy over to the fish tank, for example, which means I want to help feed the fish. By doing this I can get a lot done, and Mommy and Daddy are happy to help! By now I've pretty much replaced me pointing at something with grabbing their thumbs and having them point at it.
