Find a fairly large, open area of the house where your child won't be in danger of running into anything. Blow up a balloon and show your child how to hit the balloon into the air with his/her hands. Try to hit the balloon back and forth, counting each successful hit. Or, simply hit the balloon to your child and challenge her to catch it...counting out loud each successful catch. Children who cannot yet catch a ball are thrilled to be able to catch the slower-moving balloon.
