I know I have messed up in the past but I had gotten a rude awakening when I caught my 18 month old son grabbing my cigarettes and putting the butt end in his mouth and mimicing me. We never smoked around them but I'm sure it didn't take a rocket scientist to know how to use them. That was the last straw for both my husband and I. I don't want them to copy me. I AM SMOKE FREE, I AM SMOKE FREE, I AM SMOKE FREE, and so on and so forth.
