I was reading a book today that earnestly counselled women in the third trimester to have a 15-minute nap at work - "even in your car if you need to!". Of course, like many people, I don't bring a car to work, and I'm a teacher, so time and quiet places for naps are rare. In fact I can't imagine many jobs where you'd have the chance to nap.
Just one of those tips where they clearly meant well, but come on, if I could nap I bloody well would be!
