I feel a bit shy about these things - was the same with my engagement. Felt a bit "show-ey off-ey" even though I know its not really.
I am telling friends as I see them / as it comes up, but have a large family and need to tell them all at the same time as they got a bit funny in the past with cousins who told people as they saw them as that always meant someone was the last to know and heard from someone else
Anyway - I kinda dont wanna do it by phone - find it a bit hard to get the words out and know what to say. Got around the engagement thing by sending "save the date" cards so didnt have to do it by phone. I wanna cop out and get my mum to do it but she's having none of it (and I guess, rightly so!). What about writing? Do you think "we're having a baby" cards are a bit tacky?
In general I much prefer other forms of communication (face-to-face, internet, letters, cards) to phone conversations. I am not a phone person. My phone is used 95% of the time for texting.
