I have quit smoking while I found out I was pregnant instantly, and I was quite a heavy smoker. But I just find it stressful sometimes and I would like to go back to it (using handgell and gum afterwards so my daughter won't smell it). Is this bad, and should I just keep on not smoking after I give birth? I'm planning on breastfeeding but if that has any effect on the milk or anything I won't, and will be planning on smoking again after she's one year old.
