I've ordered some foil blankets for people's beds ready for winter as they are on offer because of the heatwave Sandwich these between top blanket and heavy blanket to keep mums and children warm. They do work . We didn't hardly have our heating on winter to the point british gas changed our meter because they didn't believe us and believed it was faulty. You cant keep the heating off with the children but you may be able to turn it off for a few hours or have it lower to save money. They can be sellotaped to windows and doors to keep heat in too . ❄️🌬⛄️❄️🌬⛄️❄️🌬⛄️
Bonus: stops cats jumping on you while you are asleep!
