A map of the United States. Which the kids are both IN LOVE with. John Paul likes to listen to his "Wee Sing America" CD and march, run, or dance around the United States (depending on the song).
It can get rather frantic. Cecilia likes to spin around the map until she gets dizzy and falls down. She told me the other day, with a huge grin on her face, "Gee-ya BINAMEWICA!" (Cecilia is spinning around America!)
