Forget about naming eyes, ears, and nose... this boy is all about showing you his MUSCLES!! When you ask him to show you his muscles, he stiffens up, grits his teeth, and shakes his little fists. The face he makes is pure determination and never fails to make me laugh:
It's a great party trick.
We're working on naming eyes, nose, mouth, ears, head, fingers, toes, and tummy. If he's in the mood to work (and that's usually a big "if,") he gets them all correct, but when he's just in the mood to play, he shows me his muscles. He's already figured out how to use his cuteness to get out of doing things he doesn't want to do!
