I agree with Dachlostar.....music CDs are the best!! There are so many on the market and most libraries stock a small selection as well. Even if you don't have any kids CDs, stick on a bit of music and dance about in different ways, stomping, clapping, tippy toes etc. My DD loves it when Grandad puts on the Rolling Stones or Beatles!! Also some things to dance with like scarfs or tape some crape paper to a bit of cardboard or paper plate and swirl around with it.

Something I picked up at Kindermusik - pretend you're a train going fast and slow, get pretend tickets and 'all aboard', WOH, WOH

Get hold of some bubbles - they love to run after them. You can buy cheap bubble machines from usual stores.

Hmmm, sure I know more, but can't think at the moment.
