DH and I decided we were not going to tell anyone when I went into labour with DD because I didnt want people waiting outside the birthing suite for me to deliver the baby. Luckily for me it was after 2 in the arvo when Tori was delievered and there are strict rules about ow many people are allowed into the birthign suites, so no one could visit untill we got back to the ward.
My mum and dad and bro and SIL came for a very quick visit the first night, but then I told them to tell everyone else that I wouldnt be taking visitors untill the next afternoon.
Luckily for us everyone was really considerate and rang first before they turned up, I had heaps of people there are one stage, but most of them only stayed for about half hour and then left DH and I have some bonding time with our daughter.
