Now I don't know what to do here. My DD has a best friend who is a really nice little girl. Recently they have started to visit each other's houses more, and here is where my problem lies - because the friend's parents smoke, and I mean REALLY REALLY smoke. Their house is the smokiest house I have EVER been in! I don't mind so much our house smelling of smoke after the friend has been here because I can air it out eventually, but after DD has been visiting her, she is completely impregnated with it - even washing her hair and clothes doesn't entirely get rid of it, and I can't wash her coat etc every day!! I do worry about what being around all the smoke is doing to my daughter's lungs, and also worry about bad examples (she's already told me out of the blue how much she likes it when someone smokes near her). Am I being unreasonable and paranoid? I really don't want to spoil her friendship, particularly as she has always found it difficult to make friends, but I truly hate the smoke.
