Okay it's COLD

It's 20 degrees outside right now and according to weather.com it feels like 3 degrees.
We've stayed indoors today because it's so cold but I've got to tell you, this apartment isn't very warm either.
Don't know if you can see this but I have the thermostat turned up to 80 and it's not even at 60.

But the kids room, that' the worst. It's about 48 degrees in there...Maybe more like 45.
Seriously? How can I have the kids sleep in there?! I'm going to have to put some towels against the windows or something...
