Well before they made it public would you congratulate them?
My Grams called last night and told me 3 of my cousins are expecting. Two of them are past 4 months but the third is only 7 wks and hasn't announced it publicly. I know (from Grams) that they've had trouble getting pregnant, and I really want to wish her well, but I'm not sure if I should wait? We're not particularly close, and I'm pretty sure if Grams hadn't mentioned it that I would have found out on FB later on.
Would you send her a (private) message of congratulations or just wait?
