I have got tshirt, cardigan and hoody on plus socks and slipper boots. I feel fine temperature wise. We have a real thermometer in the room that tells you the exact temperature as opposed to one of those colour changing ones so I know it really is 15 degrees and not any colder. Sister came round earlier and said it was freezing and that we were neglecting our poor DS in that temperature. We haven't had the heating on yet and trying to hold out until December cos of a big bill earlier in the year. Does anyone else wait until December if they can?
