Early relational health (ERH) is not a new field, but an enhanced focus on knowledge from infant and early childhood mental health (IECMH), neurodevelopment, and related fields. ERH brings attention to the centrality of safe, stable, and nurturing relationships and resilient communities as drivers for current and future health and well-being of children and families. Responding to the call for an ERH paradigm shift to reprioritize clinical services, rewrite research agendas, and establish new advocacy, the Center for the Study of Social Policy's National ERH Coordinating Hub works toward health system and community transformation by harnessing networks of stakeholders, families, and professional leaders.
