We have been teaching our toddler to identify his nose, mouth, ears, and eyes. Sometimes he'll point to one, but usually he just laughs. My husband came up with a great idea yesterday. Since he loves to put stickers on things, he told our toddler to put a sticker on his nose, and it worked! Now we are going to play the sticker game to help identify things!
I've also thought about taking a picture of his nose, mouth, etc, and then making a small photo album with the pictures. That way he can identify his own body parts.
