My DD who is 2.10 wanted to pretend she was smoking a cigarette yesterday 
The only person that she knows who smokes is my FiL. He visits once or twice a week and is not allowed to smoke inside so goes into the garden. DD knows he is going out for a 'cigarette' (because he tells her) and she often plays in the garden so will see him.
Obviously I can't protect her from seeing anyone smoke but would IBU to ask him to refrain from smoking at all while visiting? He's a chain smoker, probably can't last more than an hour without a cigarette.
I'm devastated she knows what a cigarette is already.
Or am I being precious? I also hate how stinking he is - DD is besotted with him and doesn't seem to notice though!
