Body Parts

O studies my belly intently.

Me: "Are you looking at the baby?"
O: "Yes. Where's his foot?"
Me: "I'm not sure. Where do you think it is?"
O: "I think it's here!" (poking me in the side)
Me: "Maybe! Where do you think his head is?"
O: "Hmmm....maybe over here." (poking my other side).
"But I know his bum is here!" (poking the lowest part of my belly).
Me: "Really?"
O: "Yes. So he can poop on the floor!!!"

Sigh. Why does it always come back to poop?
