Because DD's #2 and #3 don't get along, I'm forced to sleep with my bedroom door closed. That's an issue since the wall heater is in the hallway. So, I went out and bought a small heater, just enough to take some of the chill out. I also bought a humidifier. We started using one in the bedroom a few months ago and it decreased snoring (both of us) and it really made the room less dry from the cold and made sleep easier. However, the former DP finally took it and put it in his room. The upside is that the humidifier I bought makes little to no noise. The other made a noise. Score for me!
