Why?I'm a mum and used to be a smoker. I never ever smoked in the car when my daughter's in it too, I couldn't make myself.
I want her to be healthy and not get her lungs full of my second hand smoke!
It's not difficult to find somewhere to stop when you need one (and even though she's good in the car it can get pretty stressful lol) or have an electric one (no passive smoke) so you don't hurt your child.
edited cause I dont smoke any more
