Someone at work is pregnant. It's her first baby. Yesterday someone said that the first baby is typically late, while the rest are usually early. Is it just me, or if this has been happening for a long time, shouldn't they just estimate the first baby later, and the other babies earlier until they start getting it right?

Actually it's all about not getting all worried when the first baby is early, but since the due date was pushed out it looks like a bad situation. Conversely, you don't want a false sense of security when the other babies are early but it doesn't look as early in relation to an earlier due date.
