Hey you are doing fabulous! I tried to quit while pregnant, but the damage was already done. I got down to 7 a day (from a 3pack a day habit) within a week of finding out, but I was already 3 mos pregnant. My son was born at 24 weeks, exactly to the day, 5 months along.
I don't know if it was the smoking or the stress I was going through in life, but along he came, and what a ride ever since!
A child's health is mucho important, and you want to do whats best for your baby as soon as possible. (Not tryin to scare you, but these things DO happen!) Although I never went back up to over a pack a day after cutting down, even my smoking outside has caused some problems with his health. Its on you, your clothes, your skin, and yes, your hair and thats not good for any baby or child.
