ABC is a parent/child treatment approach designed to help caregivers provide nurturing care and engage in synchronous interactions with their infants. ABC helps caregivers re-interpret children's behavioral signals so that they can provide nurturance through parent coaching sessions. It was developed primarily for use with low-income African-American, Hispanic, and non-Hispanic White families who have experienced neglect, physical abuse, domestic violence, and placement instability.
