The Birth of Baby Jesus

Last night as we were getting ready for bed, I read Ethan this cute Christmas book about all the animals in the stable when Jesus was born. Since the story was more about the animals than the birth of Jesus, I had to explain to Ethan how Mary had given birth to her baby in the stable.
Ethan's immediate response, "She should go to the hospital."
"Well, Ethan, not everyone has their babies in the hospital. Plus, this was a long long time ago and they didn't even have hospitals then."
"So, Mommy, how did she get the hole in her tummy then?"
Even though I have had two c-sections, I've never realized that Ethan didn't understand babies are usually born naturally.
"Well, Ethan, most mommies don't need to have a hole in their tummies to have a baby."
"Then where does the baby come out?" This question was inevitable.
"The baby comes out of the mommy's vagina."
Ethan just stared at me. He couldn't tell if I was joking or not. The look was priceless.
"Really, Ethan. Most babies come out their mommies' vaginas. They don't need an operation for the baby to be born."
He started laughing. "How does it fit?"
Hmmmmm. How to answer that question without going into the wonders of childbirth? "Well, Ethan, that's the way mommies are made. The baby slides through and is born."
"Kinda like magic?"
"Yes, kinda like magic."
Thanks to baby Jesus for this conversation and the realization that giving birth is magical.
