Here are some activities that help him learn:
Double the fun. Ask your child to show you his fingers or his ears, then ask him to show you yours. He'll get a kick out of the give-and-take -- and from getting the answer right .
Channel Picasso. Draw an outline of your child's hand or foot on a piece of paper, then name the parts -- like the thumb or pinky toe -- together.
Quiz him. If your toddler is more verbal, a simple guessing game -- you ask him which body part helps him run, he shows you -- kicks up the level.
Don't forget old standbys. Any game that lets a toddler burn energy is a good thing. So try some Simon Says with body-based directions ("Simon says, wave your hands!"), or do the Hokey Pokey and turn the two of you around -- all the way to naptime.
