The TLC Program, unique in its focus on the postpartum period, used a researched model of behavior change that matched messages and skill training with the woman's stage of change. It also addressed the whole family to create a supportive environment for individual change, included other steps for families to protect children from passive smoke and negative modeling, and focused on smoking and smoke exposure directly as well as through self-care and child-care messages. The program used innovative materials, including videotapes and intervention.
