DD1 was before Facebook! Lol so we told both parents when we were in labour then my parents live further so I said after 14 hours don't know what's happening but they came in just in case, ended up just on time to wish us well on our way to emergency c-section. Then they came into recovery
Hubby parents came first thing in the morning and we also sent SMS in the morning. I had five solid days of visitors and my naive new mum side of me ignored rest time.

DD2 was a planned c-section then I was knocked out and my gallbladder was removed.
My mum was looking after DD1 and the rule was that DD1 got the news first then parents and patiently waiting good friends
Then to make sure no one Facebooked my news I put photo and stats up of my girl about 7 hours later (I was in surgery knocked out for about 4) I sent everyone out at rest time that time.

This time again DD1 gets the news first followed by immediate family then I Facebook for everyone else.
