WHAT?!!?

When I was pregnant with Bryson, I watched A Baby Story on TLC everyday, until the day that 3 1/2 year old Riley saw it and was shocked that "Mommies poop out the baby?!" Since he was so young and I had no earthly idea what to say at that moment, I went with that idea. Fast forward 5 years to last Wednesday. Out of the blue, Riley's curiosity returns. Here is how the conversation went:
Riley: "Mama, you know how a mommy has to poop out the baby? I bet that hole has to stretch A LOT!"
Me: (shocked and at a total loss for words) "Well, son, mommies don't really poop out the baby. There is another hole for that."
Ry: "WHAT?!!? Can you see it?!
Me: "Yes, but it has to stretch, too. Heavenly Father made a mommy's body that when it goes into labor, little by little, that hole gets bigger until the baby can come out of it."
Ry: "Man, mama, I bet that hurts worse than gettin' shot by a paintball gun!"
Me: "Son, it hurts worse than pulling a paintball gun out of your nose. Sideways."
