At this point, Turner knows what my camera is when he sees it. He knows that I'm going to be taking pictures of him so when he sees it he'll want to come sit in my lap and look at the pictures that I've taken. But he doesn't yet realize that it requires him to actually pose for pictures first. He apparently just thinks that the photos magically appear on there.
I pulled out my camera tonight and Turner, despite trying to finish up his milk, automatically started walking toward me, wanting to see his picture on the back. I would move to the other side of the room and he'd immediately follow. So, I just moved back and forth in the room until I got a decent photo of him.
