we're using an oil heater in DS's room - I'm not comfortable with him having a fan heater in there or a radiant heater and his room gets rather cold overnight as the heating at that end of our house is pretty bad. I just make sure it's in the middle of the room and there's nothing that can fall on it or touch it (unless I bump it in the middle of the night when getting up for DS and don't turn the light on and then I just push it back to where it was). Makes me feel a bit better about using one.
