I agree the article is giving mixed messages. That may have been what our mothers/grandmothers did in the 60's and 70's, but look at what research and information has come out since then as to how this lifestyle can affect baby. I'm sure that by the time my DD comes to have children, there will be even more info etc. I think that regardless if a pregnancy is planned or not, that once you find out, a main focus is to give the baby a healthy start in life iykwim.
This is going slightly off topic, but with living in the UK at the moment, I'm so surprised as to how much of a smoking culture it is over here. People smoke outside, BUT right at the entrance of stores etc. hmmm sure I want to breath in your second hand smoke as I try to get in! I've also lost count of the number of times I've seen women pushing a pram with baby facing towards them and then lighting up a cigarette and blowing everything over the baby! It def makes me wonder what else the poor baby had to endure while in the womb.
