I had an elective c-section and although our families knew we were having a c-section (DS was breech) we didn't tell them the date. I had a HUGE fight with my mother over it because she wanted to be able to organise her life around it but apart from that, everyone was fine. I loved ringing people and saying we'd had him and it was such a surprise for them. We were able to have time alone with our boy which was so special, and I was quite ill after it for a few hours (reaction to the epidural) so it was so nice not having people in my room to watch me retch and nearly pass out (tmi I know, but it's true!). It's definiately not a selfish thing - you will never get those moments back so enjoy them!
