So that's how it's done

Lily: Mama, how do babies get in bellies?
Me: How do you think?
Lily: I don't know!
Me: Make a guess.
Lily: Ummmm, eat something?
Me: Like what?
Lily: Spicy Food?
Me: [suppressing urge to bust out laughing] Is that why you won't eat spicy food, Lil?
Lily: Yeah.
Me: Trust me kid, nothing you eat will ever make a baby grow in your belly.

I then went with the "special hug that a mommy and daddy share" explanation.  She must have bought it because she immediately started asking questions about the beach.  Sweet. 

Have your kids asked that question yet?  If so, what explanation did you go with and how did they react?
