Early relational health: Innovations in child health for promotion, screening, and research.

Relational experiences during infancy and early childhood are key drivers for building health, social emotional development, and learning capacities, each vital for wellbeing. The U.S. child health sectors share a commitment to universal health promotion, prevention and early intervention, and a growing enthusiasm for the research-affirmed primacy of caregiver-child interactions during the critical first 1000 days of life. Given our nation's growing children's mental health crisis, racial justice awakening and the need to reimagine equitable supports for young families post-COVID19, the child health sectors seek new tools and clinical approaches that blend science-to-practice innovations with co-developed activities that are meaningful to families. This special section brings together papers about a journey of co-discovery between researchers, clinicians, and parents during the development and refinement of new video- and interview-based dyadic relational screening and monitoring tools. The collection of papers addresses a range of topics including early relational health (ERH), development and validation of the Early Relational Health Screen, its application within research and clinical settings, and thoughtful discussions from multiple perspectives. Informed by the diversity informed tenets, this journey highlights not only science-informed approaches, but also co-development with families of equitable approaches to understanding and serving children and their caregivers.
