Will it make you a bad mother? no
Will it make you a bad role model for your child? Depends on how you view it.
Will it make you, in the long run, not able to be around for as much of her life and her children's lives? Yes, no question.

It's not about the 'right or wrong' it's about a very simple fact. Smoking will kill you. And it will do so in a way that will be painful for you and your loved ones. You may be, and probably are, an amazing mother, but if you smoke you will be courting a number of diseases that will decrease your life expectancy. And as a mother you will be leaving that to your daughter; the fear of loosing you, the pain of watching you suffer, and the eventual loss of her parent to something that can be terrible.

Am I exaggerating? Yeah, not everyone gets lung cancer, or emphysema, or even a bad smokers cough. But enough people do that it's a concern to think about. What you do now isn't just a about the now, it's about the then too.

Am I biased because I dislike smoking? Yes. Do I condemn those that do? No. But think about this; even if you don't contract anything from smoking you're teaching your child this is a fine habit to have. And it may kill THEM. As a parent is that what you want? To know that something you did caused the death of your child?
