I have to admit I was a lifetime smoker (30 yrs) until a year ago when I was finally able to quit, but for each of my pregnancies (3 sons, all grown now) I had to quit it made me sick to smoke. That was how I figured out I was pregnant each time! I would get sick smoking before I even missed my period. My body flat out rejected the smoke! Maybe if I had kept trying I could have forced smoking, but I was to excited about being pregnant and even back then it was known that smoking during pregnancy was bad. I did however, smoke around my kids after they were born and now all three of my boys are smokers. I wish I had stayed quit after the first pregnancy even though my husband smoked. I really am sorry that I exposed my children to smoke while they were growing up and that they all are smokers as adults. That has a lot to do with them seeing there father and I smoke the whole time they were growing up and I know it. All of you mothers out there who smoke, try hard to quit so you don't raise smokers. Do you really want that for your kids? I usually hate the soap box and especially from reformed smokers but I'm just saying....
