A Study of Tobacco Smoke and Children With Respiratory Illnesses

Inclusion Criteria: * age 0 to 10 years old * admitted to The Barbara Bush Children Hospital for bronchiolitis, pneumonia, bronchopulmonary dysplasia, or asthma * the child lives with an adult who smokes cigarettes Exclusion Criteria: * Non-English-speaking and -reading adults will be excluded as our interventions are in English. * Children over the age of 10 will be excluded as we wanted to avoid children who themselves smoke, given that we will not have a confidential way to assess this. * Breastfeeding children will be excluded as nicotine is transferrable in breast milk. * Families (meaning the parent or guardian, the child, and any smoking coinhabiting caregiver) will be excluded if the parent or the smoking adult is a minor, as they would not be able to give consent for participation. * Children in foster care or whose guardian is the state will be excluded as we are unlikely to achieve timely consent. * Families who do not reside in Maine will be excluded as The Maine Tobacco Helpline is not able to provide services for out-of-state residents. * Children readmitted to the hospital during our study period will be excluded if they have already participated in this study during a previous admission.
