We have a bath book that comes with a washcloth. On each page is a different animal. You take the washcloth and "scrub the duckies, scrub the cow, scrub the piggy, you know how. Scrub the chickens, that'll do, silly chickens, now wash YOU!"
Theo loves washing the animals and then washing Melody.
This morning while Melody was in the bath I opened the book and handed her the washcloth to see what she'd do. Normally she immediately tries to eat it. But today--sure enough, she started scrubbing the duckies!
What a smartie I've got on my hands. :)
