LOL Salad! I'm with you I like clothes washing... It's dishes I HATE!
I have heard it too. FIL told me in my first pg that his mum lost a baby and she'd always thought it was because she'd hung the washing out He's not always tactful, but he was trying to be helpful I think. I too believe it's not true, just something people used to say to try to explain tragedies that occurred prior to the medical testing that's done these days KWIM?
