LO's room get's pretty chilly at night, and I'm not sure how cold is too cold, and what I can do about it. She sleeps in cozy pajamas and sometimes a sleep sack and then she has her blankie that she needs to cuddle, so as far as being cozy I think she's good but her hands are always freezing but she hates them being covered! She gets a major draft through her window and we tried getting that plastic to cover it, but it doesn't work for her window. She has curtains but they aren't that great at keeping the cool out, like ours do.

So how do I know if she's fine or if I need to find another solution?
