So Bonnie's bedroom has been only 16 degrees at nighttime lately which I think is too chilly for her. I do pile on the layers (grobag and blankets) but am in two minds about using a heater.

I bought a fancy schmancy column heater with a thermostat that I set at 20 degrees. It's super safe and effective, but it really dries out the air in the room. I often sleep in her room so when I wake up my throat is super dry. I wonder if the dryness may be affecting her as well and maybe contributing to her numerous night wakings.

So, those of you with chilly rooms - would you use a heater, or just keep the layers on without a heater?
