Lucas: "Did I eat your blood?"
Lucas: "But I couldn't eat food or drink your milk if I was in your belly and there is blood in your body..."
Me: "You know how you have a belly button?"
Lucas: "Yes, it is in my tummy"
Me: "Well when you were in my tummy there you had an umbilical cord there and it attached to mommy and that is how you got food"
Lucas: "What kind of code?"
Me: "No, not a code. A CORD. An umbilical cord. When you were born the nurse cut the cord and tied it into a belly button."
Lucas: "So just boys have umbilical codes?"
Me: "No girls do too. All people had umbilical cords when they were a baby and some animals do. Some animals don't have them because they hatch from eggs"
Lucas: "Do dogs have belly buttons?"
Me: "Yes, but you can't really see them because of all their hair."
Lucas: "Mom, that is crazy. You are telling me I used to eat with my belly button!"
