I try not to link too often to items found on BoingBoing—they get plenty of traffic already, and everyone reads them, so why bother? But I found this recent rant—about due dates and statistics—fascinating. It’s the kind of thing I should’ve been obsessed about when Sasha was gestating but somehow forgot to be:
Petunia was getting bigger. Her bones were hardening. Her eyebrows were growing. She had a July 11th due date, and, though there was not much I could do to influence anything, I could, nonetheless obsess about what, precisely, a due date means. I asked anyone who I thought might have some insight. I know, for example, that due dates are simply calculated by adding 40 weeks to the start of the mother’s last menstrual cycle. But how effective is that? How many babies are born on their due dates?
Our child birthing class teacher: “Oh only 5% of babies are actually born on their due dates.”
Me: So are half born before, half after?
Teacher: “Oh you can’t know when the baby is going to come.”
Me: I get it. I just want to know the statistics.
Teacher: “The baby will come when it is ready.”
It goes on from there. If you like science or statistics or are just a whacked-out obsessive nut job like this BoingBoinger and me, you might like.
