My poor kid has a freezing bedroom while the rest of the house stays toasty warm. It's ok when the heating is on, but I can't leave it running all night (expensive system) and the rest of us would boil as I'd inevitably forget to turn down the other rads and none of the other rooms need heating through the night.
I've considering double layering pyjamas, or doing a thermal layer with a fleece onesie, but as the room isn't cold at bedtime I worry that this would be too much for the first few hours.
The room has thick, lined curtains and bedding is 13.5 tog duvet with a blanket when necessary. The floor is laminate. Would changing this to carpet help? What else could I do?
