This has got to be the cheapest and easiest entertainment. I only do it when the boys have guests over for the afternoon.
When the kids need a little down time from playing hard with their friends I break out the sugar cookies, frosting, and sprinkles. They each get their own small bowl of frosting and choice of sprinkles to decorate as they please. It's quick, easy, and the boys love it.
So tie on your apron and get to baking! It's summer and you know you have a few play dates headed your way.
