OK you can all slate me if you want as I haven't been pregnant myself and am only basing this on instinct rather than any fact.
However a friend and colleague of mine is 13 weeks pregnant and has been 'banned' by her dh from walking anywhere while it is snowy, including to work which is a 15 min walk for her. They don't drive so she has been housebound all weekend. We live in london so it's not a case of 10 feet drifts. She is quite happy to go along with this, and is planning on getting a taxi tomorrow instead. I'd have personally thought that driving in the snow with an unknown driver is more dangerous than walking.
I know this is non of my business really, it's just that I'm getting a but fed up with her extreme preciousness since she's been pregnant (she was generally sane before!). I've had a number of friends and colleagues who have been pregnant and I've never been irritated by them being cautious about various things before. It's just her and her constant pfb behaviour before they are even here that is driving me mad!
Ok rant over, and as I said you can all give me a virtual slap if you like.
