Will it harm my baby if I smoke one cigarette after I pump at work?

so there's no way my baby is exposed to the smoke.... Yes there is, you smoke and feed. I am sorry, but you need to chose one. Why would you want to go back to smoking and expose your baby. Especially when you are un sure on the risk? Stop now.. Do you even think about how your baby will feel if he/she loses her parents to cancer?
