Baby Bath Bring out your tot's water-safe baby dolls, soap, and some small sponges (kitchen sponges cut into thirds work well) and let your child scrub her pals clean. Older kids can also wash the dolls' clothing and hang it on a low clothesline to dry.

Water Park Along with several shallow containers of water, set out such items as funnels, clear plastic tubing (available at hardware stores), cups, and pipettes and encourage your child to experiment. For a twist, add a little color to the water.

Car Wash Roll out your child's collection of ride-ons and other vehicles, then offer sponges, spray bottles, and no-tears soap.

(Remember to closely supervise your child around water.)
