The Proof is in the...

I had an OB check-up yesterday and the boys went with me. Laurence didn't say much about the appointment, though I know he enjoyed when the nurse, medical student, and doctor all asked him whether he'd like a boy or girl. Each time he responded, "A brother would be fine, but what I really want is a sister!" Then last night at dinner he says, "Mommy, I thought you were kidding about a baby being in your belly until today when I heard the heartbeat. Now I know it's real!" Awwww! So sweet, but I do wonder...how could he not believe me when I look like this? -------------------------------->
