What's a Due Date Anyway???

It's just an estimate, and apparently not a very accurate one either. I mean what are the chances that I'd be 2 for 2 with going later than my due date. Inaccurate due dates or stubborn children? You decide.

PS: Of the 20 of you who gave me a birth date guess, 14 of you have already lost. Only 6 still left in the running!
