AIBU to think there is FB etiquette when it comes to birth announcements?

[Sharksandfishes]

DS2 born yesterday. We are in Australia so had to wait for the time difference to kick in before we could tell all our close family. My mum was one of the first people we spoke to and got v excited and text all her friends. A son of one of her friends posted congratulations on FB.
Then we Skyped BIL, SIL doesn't normally bother to speak to us on Skype. Today was no exception. She came and had a look at DS, said "ahh" and then nothing.
Then she posts a bloody message on FB saying congratulations. WTF? If you can't be bothered to speak, why would you do this??

Isn't it normal to wait for a birth announcement before you post? Or am I being emotional and hormonal?

YANBU I had to delete comments abouts my pregnancy off my fb wall at 7 weeks, having previously had 2 mcs I wasn't ready to announce it to the world but some people needed to know as we were doing a 26.2 mike charity walk when I would be 8 weeks and I needed their support.

I would personally never post about somebody else's news until they had posted the news. It's common courtesy imo.

If etiquette applied to facebook, it would be this. Stop thinking that you are so important and that everyone wants to hear about you. Narcissism is wrong.

Facebook is like being at a dinner party from hell where everyone just talks about themselves non-stop.

I don't personally do it before an announcement, if no announcement I wait for the new mum to respond to previous congratulations before I leave mine.

I do think a lot of hassle and upset would be saved though if you just turn commenting off on your wall a week or so before. That way no one can put anything public before you want them to. You can always turn it back on and then write something yourself if people want to leave congratulations messages.

There is a thing on FB called PRIVATE messaging.

Personally I think its underrated and underused.
