I am an ex-smoker, and have 2 children. Going through childbirth was FAR easier than giving up smoking. Good on you for stopping, and congratulations on that fabulous news!
At the end of 12 months of non-smoking I bought myself an 18 carat gold bracelet, which was still much cheaper than 12 months worth of smoking!
