Okay so you said in your first post that no one has funds until the beginning of the year --- do you think you would only have to live without electricity until then? So, say December 17th until say, Jan 10th or something? So that would be about a month.
I think if there is no possible way at all to avoid this -- no one to stay with, no option whatsoever -- it can be done. Do you have a source of wood for your fireplace? Is your chimney clean? You have to make sure that the *bad* part of combustion is escaping -- you just want the heat, not the gases. People have been heating with fireplaces for hundreds and hundreds of years. Do you have a carbon monoxide detector? Move it to your family room - this will help you feel more secure. If not, I would scrape together *something* to get one for your piece of mind and safety. I think fire departments give them away for free -- you don't have to reveal the details of why.
Move the bed to the family room -- or a mattress. CPS is a concern but we are living in really tough times -- so I would make the family room appear as much like a studio apartment as possible -- keep it clean as possible -- even move a dresser in there too with some of your clothing so that you can get dressed and such near the fire. How will you do laundry? Do you take it someplace now? People do laundry by hand even now but that may be too much for you, being pregnant and whatnot. I would just try to create as few dirty clothes as possible.
Can you heat water on your fireplace? I would have a big bowl to pour warm water in for quick cleanings because you won't be able to take baths and such -- The kids could probably bathe in a big rubbermaid or something near the fire. An alternative would be to heat big pots on your grill if you can and keep it wrapped in a blanket with the lid on to retain heat while inside. It is possible to stay clean by spot-washing (they do it for the infirm and such in nursing homes, you just have to be very conscientious). The thing is, if you were to be scrutinized by CPS for any reason -- you want to make sure the children are always clean (even cleaner than most people do now to overcompensate for your unique situation) -- that the family room doesn't appear like a squat but as a studio apartment how many families did in winters.
Food -- eat as many shelf stable things as possible so you don't have to worry about cooking and cooling -- peanut butter, bread, canned veggies -- things of that nature -- fresh foods can be kept in colder parts of the house (like raw veggies and such).
If you can, take advantage of heat elsewhere -- the library, malls, things like that. You can spend a ton of time in a bookstore for example.
Tape plastic over the windows in the family room and hang blankets over that to keep heat inside -- close off the entry to the family room if you can. Again, it is important to appear that this is all very intentional (even if it isn't sadly).
I think if there is seriously no option, you could do it. I am just very sorry you are facing this -- but like most things I do believe if you set out to thrive in spite of this, you can -- especially if you know it is only temporary.
Good luck mama -- and honestly, the FIRST thing would be to make sure the chimney is clean, make sure you have clean wood to burn, and GET THAT CARBON MONOXIDE detector.
Sadly, this is becoming more common in this economy
