I dont know of any articles to point you in the direction of but I was under the understanding that smoke on clothes could be harmful to babies. Even if its not then the smell would surley upset the baby. I am an ex smoker and smelling it on someones clothes now makes my eyes itchy and my nuse runny so I can only imagine what it would be like for a little nose that only knows the smell of its mum IYKWIM?
I definately think its worth fighting for. It is your child. Your dad should be more understanding towards your concerns and his grandchild.
Yes you turned out fine, but research and studies have come along way to help protect and support these babies. The sids rate has dropped dramatically since all these preventative measures were put in place.

A bit off topic but still relevant I guess, when I was born in 1982 in Queensland, it wasn't the law to have your children in a properly fitted restraint. I was bought home in a moses basket on the floor in my dads ute. Now research and the law now state that all children under a certain age and weight must be restrained in a prperly fitted age appropriate restraint.

I guess Im trying to say that things change over the years and what may have been ok once upon a time, isnt ok now.

Sorry for the rant - I hope I made sense. I just got really passionate about it xx
