Do you know where babies really come from?

Lauren is always talking about how baby Claire came out of Mama's tummy, and how Dr. Atkins helped me get her out. One day a few weeks ago, she was saying this again, and I asked her, "Lauren, do you know where you came from?" She looked at me and said "I came from Costco!"
I told this story to a friend, and she laughed and replied "if Lauren came from Costco, she would have been quadruplets..."
