In Utero

Jason, snuggling with me in my bed: "Mommy, did you know I used to be in your belly?"

Me: "Yes, I know. What was it like in there?"

Jason: "It was cool and wet, and there were lots of bones!"

Me, obviously concerned at the thought of my child being cold: "You were COLD?!"

Jason: "Well, I was swimming so I stayed warm."

Me: "There was enough room to swim in my belly?"

Jason: "Yes! I swimmed and swimmed and it was so much fun!"

This explains a lot of the discomfort I felt in the third trimester.

Me: "What else did you do in my belly?"

Jason: "I played. With a train."

Me: "Where did you find a train in there?"

Jason: "I brought it with me."

Me: "..."

Jason: "I ate some food, too."

Me: "What kind of food?"

Jason: "Corn on the cob."

And there you have it. You always wondered, and now you know.
