Hi all, we have just found out my sister and BIL have had their baby, they told both sets of parents but not siblings, baby had only been born an hour and one of BILs colleagues has posted a message congratulating them, we've seen the Facebook post before we got the message from my mum telling us the baby had been born, AIBU for being upset? I haven't told my sister I've seen the post as don't want to spoil their special moment but I'm still hurt that this has happened, I know it's the colleagues fault for announcing but am annoyed with BIL for telling a colleague before making sure all family know! WWYD? X
