We are finding out the sex of our baby today, but we're going to have it sealed in an envelope so we can be surprised with our family on Sunday. We plan to use cupcakes to reveal the sex by filling one or all of them with pink or blue frosting. We'll all bite into them together. My question is this: should everyone get a cupcake with colored frosting?  Or should there be only one cupcake out of the 15 cupcakes that had colored frosting to heighten the "suspense" and fun?
