Today is our anniversary, so we had a family supper to celebrate. My three year old son asked if we got married so that we could have him and his brother and we told him yes. Then he asked how babies are made. I pointed over to the kitchen and said "It is like when you make a cake with mommy. You take an egg, add some cream, and put it in the oven. Then it bakes, and out comes a baby." That will hold him for a few years.
