Quit Smoking as soon as possible. When you smoke, you risk not only your health but that of your baby. Smoking increases the risk of miscarriage, low birth weight and pre-term delivery. The sooner you quit smoking, the better it will be for both you and your baby. Children in a home where someone smokes (even if that person only smokes outside) are more likely to die of S.I.D.S.-Sudden Infant Death Syndrome. If you need help quitting, please talk with us.
