I love it when literature comes to life, so when my girl asked me if we could play Princess and the Pea after reading the book, I said, "Absolutely!" In the book, the princess slept on 20 mattresses. We opted for 20 blankets instead. Also, in our version there was both and Prince and a Princess who laid upon that pea. I'm not sure the kids could actually feel it, but they were great at tossing and turning!
