I am so happy to be reading this, as I never thought to check for that. I do have a smoke free daycare, but never considered the parents smoking in their home as a possible nuisance. I am too slightly allergic to smoke. I have one dad who smokes (not in the home or car) but when he comes to pick up his daughter, his smell lingers in the home...yuck! To sunflower, good luck sorting this one out, it's tricky but you have to think of yourself and the other kids primarily.
