We will provide half of the subjects (parents/caregivers) with access to assistance from an asthma coach for 18 months (including 2 contacts with an asthma nurse during the first 6 months). The other half of the subjects will not have an asthma coach, but their children will have their usual routine care with their primary care providers. The nurse and coach will help the subjects learn more about caring for their children's asthma and improving interactions with the primary care providers for their children.
