I put on one of those oil heater things and it really warms her room up well. I dont put it up too hot, but just enough to take the chill out of the air. She wears a long sleeved spencer thing and either a Wondersuit or a fleecy suit. I then wrap her in a thin wrap and then into a sleeping bag. I didnt used to use the bag, but since using it, she has been sleeping for longer at night.
