The water is poured from the bucket into one of the baths, jugs are filled and their contents emptied into bowls, which are in turn emptied into the other bath. She spends AGES doing this. When she's ready to move on, a dolly and a washcloth turn it into a role play game: Eden is now the Mummy bathing her baby!
It's so easy to set up something like this, and the towel soaks up most of the spillage, reducing the clean up time. If your child is a bit younger, just pop some simple items in a baby bath and watch them go! Things like bouncy balls, small food containers (or just the lids), wooden spoons and unused sponges tend to be a big hit for the under-two age bracket.
Given that summer is fast approaching, I think this form of water play will be given a good run!
