Luke: "Mom, how does the baby get in your belly?"
Me: "Daddy and I make a baby by giving each other a special hug."
Luke: "Can I see the special hug?"
Luke: "Well, when can I see the special hug?"
Me: "Uh. Well. Hmm. You can never see Mommy and Daddy do the 'special hug.'"
Me: "Because it is private."
Me: "Uh huh. But maybe I'll get you a book about it. Soon."
The end of that conversation . . . for now.
