We told my mum and stepdad as they would be looking after DD1, and four of our friends (two live next door so would have noticed mum's car here lol). Once we called everyone when DD2 was born and said I'd been induced, we got quite a few "Why didn't you tell us?". But like you, I didn't want the phone calls and I also expected it would go a lot slower than it actually did. Nobody took any real offense. Well as far as I'm aware anyway.

As it was, DD2 was born at 1am so we didn't tell anyone other than mum until much later!
