Where do Babies come from?

Today I was walking with Jake and Bailey and Jake asked me when I was going to have a baby in my belly. I told him I wasnt sure. He then asked me,"Mom, how do you put a baby in your belly? How do you make it?" I said,"Well God makes it Jake and youll learn more about that when you get older." He said, "But mom, where does God get all the parts for it?" Oh, to be young and naive. Kids say the darndest things.
