Awe I hear ya ! One thing too about all that social pressure is that it apparently (heard it in child birthing class) doesn't help at all because the mama feels pressure and like all eyes are on her which freaks her out and so her labor goes continues being delayed, slows or stops.
I'm a very blatant person so I'd problly put up a FB status telling people to back off because I love them but their constant reminders irritate me and don't help. XO lol
Perhaps you can just put up a post saying it in a nicer way?
