We haven't even been here two weeks but I think my son is waking up 3x at night because it's SO cold in his room. It's really warm in the open room (kitchen/dining/living) and our bedroom but for some reason his room feels ten degrees colder. Our apt faces the east, as does his window. We checked the window and it seems to be sealed. We opened the vent etc

We haven't had the heat on because it's been warm, except his room. I'm having to turn the heat on (which I hate unless I need to) just because his ears and hands are so cold when he wakes up.

Anyone else have this issue or know what I could possibly do to solve it? I feel so bad that he is cold.
