No, just turn down the thermostat a few degrees, I usually air out the daycare space before the kids arrive, then I slowly raise the heat,as the added bodies warm the house anyway.
We usually have the house at 70 but when the kids are here I turn it down to 68 and it usually goes up a few degrees when the kiddies are running around.
I haven't found the heating bill to be any different.
Awesome! I'm going to try it! I'm all for anything that keeps those germs away!
Children are great imitators.
So give them something great to imitate.
