As the title says, how soon was it before you shared your news?

My bro and sil had a baby at 11.30 last night, and called people at 2.30am. If that were me I either would have called immediately or the next morning, not in the early hours of the morning when people would have been super fast asleep. With ds he was born at 1pm, dh called his mum and my parents about an hour later but they were both with lots of people so I ended up with a thousand people in the birthing room almost immediately. I hated it and it was so opposite to what we wanted. This time I don't want to tell anyone until I'm ready but Dh thinks I'm a bit of a grinch given that I also don't tell a soul when I go into labour.
