I had said I didn't want anyone knowing I was in labour, but then I had an induction immediately after a check up with my OB. Mum knew I had the appointment so I had to tell her I was being induced. If she had waited in the waiting room she would have been waiting for 35 hours - tell your ILs that!!! We called MIL and my mum about an hour after DD was born (10.15pm) and invited them to visit the next day. DH's sisters were told (via MIL) to come only in the early evening and WITHOUT their childern (5 boys under 8 between them). Needless to say, I was furious when they all showed up with their children at about 3.30 pm. My parents and grandmother live 150kms away so its not as if they could just pop in and I was so angry that our wishes (DH agreed with me) were ignored, and that my folks had to share their precious time with their granddaughter. If it happens again this time, I'll be far less polite than I was with DD!! I ended up at one point with 11 adults and 5 children visiting all at the one time

I think at the end of it it doesn't matter if you actually are being unreasonable (and I don't think you are being unreasonable at all). Its your baby, your labour and your new family and whatever you want should be accepted by everybody. Like the others have said, I would be leaving instructions with the hospital staff that no visitors were to be admitted until you told them otherwise.
