This article explores the essential relationship needs and capacities of infants, parents, practitioners, and supervisors in a story about reflective practice. The author shares her experience supervising a home visitor who is a trainee in an infant mental health intervention program. The home visitor's relationship with her supervisor was a catalyst to forming a safe, supportive relationship with her client, who in turn was able to develop a warm, nurturing relationship with her infant. Together, they discover parallel issues and experiences that reverberate in each of the relationships: parent-infant, parent-practitioner, and practitioner-supervisor. It is this discovery that fuels the work of infant mental health and allows the intern, so new in her role, to offer a strong and meaningful preventive intervention.
