Bedtime conversation

While I was snuggling with Jack at bedtime tonight, out of the blue he asked me,
"Mommy, How did you get pregnant?"

Mommy: (Uh. Stall. Hmmm. Wasn't expecting that one.)

Mommy: "Well, Jack, Mommy & Daddy love each other so much that God decided to bless our family with another baby."

Jack: "Oh. Ok."

(Pause)

Jack: "Mommy, your face is getting fat."
