The key to a woman's baby is through her belly button.

My little 3 year old boy has a magical and interesting perspective on the female body. He asked my wife the other day, "Mommy can I feel the baby?". My wife said yes and so M approached her and proceeded to stick his finger into her belly button. My wife was somewhat puzzled by this action. Until my boy's eyes got real big and he said with his finger still in her belly button, "Mommy! I feel it. I feel the baby!". He believes that he can touch the baby through Mommies belly button. We refuse to tell him that's not how it works.
