I noticed our electricity bill is skyrocketing since it's getting colder and we need to keep our heater on. Unfortunately, we have central heating so we can't just heat the rooms we use. If it wasn't for L, we could keep the thermostat around 67 and just wear extra layers, but b/c of her, we're keeping it around 70. Do you guys think it's safe to turn on a small space heater for her in her room? I'd keep it on low, and it's brand new.
