With my DD I told everyone the date of our CS, my parents and MIL waited at the hospital with me and DH until I went in then they were asked (by me) to wait in the cafe until DH went to get them (or call them on their mobile) and bring them up. They had strict instructions that no-one other than DH was to see baby until I returned from recovery and was able to bond with and breastfeed baby, I too wanted to introduce her with DH as a family. It turns out that my baby was in distress at birth and needed to go to NICU so it never mattered in the end. This time around if I end up having a CS I will be happy to tell everyone the date but the same rules stand.
