My sis had her first bub at about 1am, and within a couple of hours I, my mum and other siblings were there to visit - she wanted to show him off! But, she was still a bit knocked out from the epidural and trying to feed, so nobody held him at that stage (even her DH hadn't held him yet). We were back again after lunch the next day. She had told friends to wait until day 2, but decided at the time she was happy to see them in the afternoon.

I like to think that people will respect what you decide (as my sister's friends did), but I know that's not always going to be the case. Just be strong in whatever you decide, and if you do tell them to wait, you can always change your mind if you want to. It's probably easier for them to expect to have to wait and then be allowed in sooner than the other way around.
