I am the last one to know I don’t have kids. But i can’t imagine official advice ever being to not wear them it’s far too dangerous advice for anyone to ride in a car with no seatbelt. And again think of the insurance u probably wouldn’t be able to afford a kid if you drove while pregnant and officially didn’t have to wear one!I think a lot of people stop wearing them but it’s so unsafe! If she wasn’t wearing one then Well done because all of the sheep will think it’s okay now. As far as I know you only have to put it underneath your belly so that if you were in a crash it doesn’t pull right across your bump I’m still confused why she didn’t just stay home though if she felt so ill. If she wanted fresh air she could have gone in the garden..
