Mercedes' Great-Aunt Laurie brought her some seashells the other day. They were kind of sandy, so I set Mercedes to work cleaning them. I gave her a couple of little sponges (kitchen sponges cut into strips) and a washcloth for drying.
Look at those squeaky clean, shiny seashells!
This has become a favorite activity at our house. She frequently asks me if she can have some water to "give the seashells a bath".
