it seesm like I'd have an even easier time than most of you ;) because I wouldn't mind taking milk from someone who smoked. I smoked most of the time I was feeding ds (bar the first two weeks). So as long as I knew they had a comparative habit to mine- less than 10 a day- and waited at least an hour after smoking before expressing, it wouldn't bother me. As others have pointed out, comparative lifestyle factors would be the key. Breastmilk is still better than formula, smoker or not (in my eyes, anyway).
