Despite the return to high temperatures today (high 80s) at night it has been getting very chilly. The kids woke up a few nights ago needing an extra blanket. We only heat with wood, and heat sparingly at that, so as the weather cools we begin pilling on the wool blankets and comforters. The first winter we lived in our home, the upstairs was just a shell; roofing and plywood without insulation. Downstairs we had the strawbale walls to keep the heat in, plus the thermal mass of the floor, but upstairs was cold. Some nights I would look up and see frost on the ceiling. We kept the kids in warm jammies, under mounds of blankets, and put hot water bottles on their feet, so it was tolerable, but stressful. This winter should be a lot more cosy, with ceiling insulation and dry wall in.
