An evidence-based prenatal cessation program that helps women quit smoking and stay quit even after the baby is born. As a reward for quitting smoking, the moms will receive free diapers for their newborn baby for up to 12 months after the baby is born. Four brief appointments with Whitaker are required before the baby is born. A carbon monoxide reader is used to measure the amount of CO gas in the breath of the participants. Once the mom is smoke-free and remains smoke-free, she is given a $25 voucher each month for a year to purchase diapers at Wal-Mart.
