I've only told my best friend who's recently had her first and a girl from work who's 5 months pregnant and I don't intend to tell anyone else!
My mum passed away a couple of years ago so that's not an issue, I'm not sure how she would have felt. I have to say, I'm really nervous about telling my dad when the time comes. I'm worried he'll think 28 is too young for me to have a family and he still has alot of expectation for me career wise and I'm worried he thinks I'm caving in and not focussing on work after all my years studying and training. Having said that, he was great when I told him I didn't want to be a lawyer anymore so who knows?
As for my sister, I've said that we'll probably start trying sooner rather than later so it doesn't come as a total shock but I wasn't telling her we were already at it, don't want the pressure!
Haven't told anyone on OH side and don't intend to - his mum would be thrilled, his dad will be worried we'll morph into personality void people and his sister will be happy - his nan has already told us they're not worth the hassle and we should just stick to dogs!!
