What would you do if you saw a very pregnant woman smoking? My son and I saw a 7+ month woman smoking (My so is 5:) ) He got very upset and said mommy if smoking is bad for you, what about the baby in her tummy? I told him it was bad for the baby, he became more upset and asked why I would not do anything. Frankly, I did not know what to do. What would you have done?
