I didn't know that. I remember thinking, when the Young Master was newborn, that the recommended temperatures for rooms (which is 16-20 deg. C, comfortable wearing light clothing) seemed a bit low, especially considering the heat in the hospital. The upstairs room I'm in is now about 60 deg. F, downstairs it's
17C (up a bit from when I came in, 'cos I've had the door open!).
