Early Relational Health: Building Foundations for Child, Family, and Community Well-Being.
Show detailsEarly relational health, or the dynamic process of mutual, meaningful, and affirming moments of connection in the youngest relationships, is foundational in shaping lifelong physical, behavioral, and mental health. These early relational experiences, expressed through varied cultural pathways, serve as a key ingredient of early learning and well-being. They shape brain architecture; regulate stress physiology; and scaffold emotional, behavioral, cognitive, and physical development. Early relational health also can buffer the impacts of adversity and build resilience (Bethell, Gombojav, & Whitaker, 2019; Esposito et al., 2017; Felitti et al., 1998; Garner et al., 2021; Hambrick et al., 2019; Morris et al., 2017; Oh et al., 2018; Sege & Harper Browne, 2017; Stein et al., 2013; Traub & Boynton-Jarrett, 2017). Importantly, the development of early relational health cannot be separated from the broader health of families and communities. Though poor early relational health does not prohibit the possibility for health, well-being, and flourishing across the lifespan, early relational health plays a powerful role in promoting lifelong well-being.
Communities, families, and caregivers across cultures and backgrounds have long understood the importance of connection and relationships for human development. Researchers, clinicians, and practitioners in disciplines across the developmental, educational, health, and social sciences have focused on these early relationships as a seminal source of wellness and flourishing.1 Rooted in long-standing family and community perspectives and scientific understandings, the concept of early relational health has been introduced more recently as a framework and orientation. It recognizes that children's flourishing reflects the collective commitment of families, communities, and society; and when relational challenges emerge, they present opportunities for community- and society-wide relational supports, healing, and recovery.
This report spotlights many streams of knowledge related to human and child development, infant and early childhood mental health, early childhood physical health, education, learning, cultural anthropology, and neurodevelopment under the encompassing framework of early relational health. Its purpose is to highlight the contexts and conditions that advance early relational health and to offer guidance for integrating early relational health into research, practice, and policies to support the health and wellbeing of young children, families, and communities.
STUDY SCOPE AND METHODS
In response to a request from the Centers for Disease Control and Prevention, the National Academies of Sciences, Engineering, and Medicine's Board on Children, Youth, and Families convened an expert ad hoc committee to examine early relational health determinants of future health and well-being for infants, children, and families. The committee was to focus on future directions for research, policy, and practice to advance early relational health within health care, childcare, education, and other community settings.
The committee was tasked with carrying out this study and producing this consensus report on a rapid timeline. It included individuals with expertise in the areas of child development, pediatrics, infant and early childhood mental health, child and family policy, neuroscience, psychology, parenting, and cultural research. See Box 1-1 for the full Statement of Task.

Statement of Task.
Study Scope
Early relational health is an umbrella term encompassing a myriad of constructs all sharing the goal of describing the relationship between infants and toddlers and their parents, caregivers, families, and community members (Dumitriu, 2024); see Box 1-2 and Chapter 2. In 2021, the American Academy of Pediatrics (AAP) adopted a policy statement reorienting pediatric care toward the promotion of early relational health (AAP et al., 2021). It defined early relational health as stable and nurturing relationships early in life (Garner et al., 2021). The AAP's definition has since been endorsed by the Canadian Pediatric Society (Williams, 2023) and by the Paul Ramsay Foundation's early relational health research roundtable in Australia (Coffin et al., 2022). Other groups have suggested variations to the AAP's definition. According to the Burke Foundation, early relational health is an emerging vision that organizes the science and practice of human relationships during the early years of life and derives from moment-to-moment interactions between parents and caregivers with infants and toddlers (Li & Ramirez, 2023).
BOX 1-2
Early Relational Health as an Encompassing Concept.
Building on these definitions, the committee outlined a broad framework to orient its report. Early relational health, although not a new concept, emphasizes early relationships as a foundational aspect of the developmental process that shapes future health and well-being. It is an ongoing, dynamic state that evolves with iterative contextual, cultural, and social experiences. From preconception onward, early relational health can be conceptualized as emerging within the ecological network of relationships surrounding infants and young children, co-constructed by caregivers, families, communities, and cultures (Condon, 2024; Frosch et al., 2021; Li & Ramirez, 2023). Early relational health is the state and practice of nurturing, safe, and responsive relationships that build emotional security, trust, mutual delight, and grounding through connection.
The concept looks at the overall quality of nurturing and responsive caregiving in the youngest relationships (Charlot-Swilley et al., 2024). It encompasses a dynamic process of mutual interactions or connections among people (e.g., parents and young children and their families), places (e.g., cities, farms, and parks), cultural communities (e.g., faith-based groups to neighborhoods), and society, with systems such as childcare and education. These moments of connection can occur in any contexts where children spend time, such as in families, in care settings, and in communities. They may include shared activities such as reading aloud, storytelling, play, or interacting with nature.
The committee's understanding of early relational health emphasizes that all relationships are shaped by the cultural contexts in which they occur. Therefore, early relational health is viewed through a cultural lens that shapes how families perceive infants and informs the various observations of multiple family–infant interactions across distinct cultural communities (Bornstein, 1991; Harwood et al., 1995; Keller, 2007; Rogoff, 2003; van Ijzendoorn & Sagi-Schwartz, 2008; Wesner et al., 2025). In this regard, early relational health is understood and achieved through a range of cultural pathways in the early years. These early relationships shape lifelong health, learning, and well-being for both children and caregivers, and are foundational for flourishing families and communities.
The committee also recognizes that there is a sensitive period early in life when the biological systems that are necessary to support early relational health develop; see Chapter 2. Given this early window of opportunity to support the development of relational health, this report focuses on early childhood systems that engage young children, ages 0−5, and their families.
The committee chose to emphasize a strengths-based approach to early relational health in its report. Such a perspective seeks to ensure opportunities for positive development, mitigate the effects of current adversities, and cultivate the adaptive capacities necessary to cope with future stressors (Brody et al., 2016; Flouri et al., 2015). This approach fosters resilience by supporting strong relationships as well as leveraging them to address current challenges and equip individuals, families, and communities with the tools needed to flourish amid future adversities. This contrasts with the toxic stress model that is problem focused, highlighting the adverse biological effects that emerge when emotional and social buffering systems are insufficient or absent. The term toxic stress refers to a spectrum of biological responses—encompassing molecular, cellular, and behavioral changes—that result from prolonged or intense adversity in the absence of mitigating social-emotional buffers and protective relationships (Shonkoff et al., 2012). The impact of such stress-related adaptations may be perceived as either health promoting or maladaptive depending on the context in which they occur and how adaptations are processed. The committee notes, however, that much of the existing research base has been framed as risk related; thus, some of the literature reviewed in this report reflects that lens. However, moving forward, research will need to be more cognizant in understanding and promoting family and community strengths and resilience; see Chapter 6.
Resilience, a term used widely in both research and practice, is “a set of social and emotional skills that allow children to adapt to future adversity in a healthy manner” (Garner et al., 2021, p. 11). Some scholars have argued that using this term can unintentionally shift focus away from the system-level factors that contribute to adversity, placing the burden of adaptation and recovery on individuals rather than emphasizing the system-level conditions needed for flourishing (McLean et al., 2024). From the committee's perspective, early relational health offers a pathway toward the scalable promotion of health at the individual, family, community, and society levels to build resilience.
Given the committee's charge and timeline, this report briefly summarizes key themes from the available knowledge on early relational health. It relies heavily on recent metanalyses and other scoping reviews, as appropriate, but it is not exhaustive. Furthermore, the committee outlined policy and practice opportunities across multiple ecological levels and sectors that together may advance early relational health. Many of these opportunities center on the public health and health sectors as these systems almost universally reach young children and their families and have potential for supporting early relational health and connectedness for young children, families, and communities. While actionable areas are identified, they are not exhaustive. Additional efforts and opportunities are highlighted across other child-serving and early childhood systems, including but not limited to the domains of early care and education, child welfare, and family support.
Study Methods
The committee held five meetings and conducted additional deliberations by electronic communications during the course of the study. To support its information-gathering process, the committee solicited perspectives from a variety of interested parties, including the study's sponsors; academics and researchers; and organizations representing parents, families, and communities, as well as federal and state government leaders. Interested parties were asked to provide guidance on advancing early relational health, including existing and emerging best practices; current opportunities to advance local, state, and federal policies that can support early relational health; and suggested directions for future research to advance early relational health and next-generation flourishing. Such perspectives were gathered through presentations or written memos and were used to supplement the committee's expertise.2
Information-Gathering Themes
The information-gathering process revealed some common themes, which served as important context for the committee's deliberations and are reflected in its conclusions when justified by the evidence reviewed. Salient themes presented by authors and speakers include the following:
- Both the science of human development and the importance of relationships are irrefutable. Research across the fields of child development, child health, child psychology, mental health, early education, neurodevelopment, family studies, and the social sciences affirms a foundational role for early relationships in human development and meaningful experiences. The convergence of these many streams of knowledge underscores the need to translate what is already known about early relational health into effective policies and practices.
- Supporting the well-being of caregivers can create conditions for early relational health. Young children cannot thrive if their caregivers are struggling. Accordingly, policies supporting paid family leave, health care coverage (including Medicaid expansion and extended coverage for pregnant women to 12 months postpartum), doula access, mental health payment parity, and community-based parent support are all examples of policy opportunities to create the conditions in which early relational health can flourish. In addition, efforts to address social drivers of health benefit early relational health.
- Relational approaches grounded in family, community, and cultural perspectives offer community-based pathways to flourishing. Cultural continuity, narratives, extended kinship networks, and relational worldviews align with early relational health principles (Boyd, 2025). Nature-based learning and Indigenous frameworks of kinship with land offer relational models for fostering early relational health for some ethnic and cultural heritage groups. These models may be underleveraged in conventional early relational health approaches but may offer important learning for health in other communities.
- Social connections influence early relational health. Early relational health is influenced by a constellation of relationships, within both formal and informal systems. Examples include relationships involving early care and education systems, educators, coaches, and other significant adult relationships in the community; family members' workplaces; digital environments; and the norms and values embedded in national policy, among others.
- Relational health requires advancing system-level supports. Scalable, evidence-based models (e.g., HealthySteps, Reach Out and Read, PlayReadVIP, evidence-based home visiting [Nurse-Family Partnership, Healthy Families America, Parents as Teachers, etc.], Attachment and Biobehavioral Catch-up, Family Connects) are available, but they require supportive financing, data infrastructure, professional development pipelines, cross-sector leadership and coordination, and consideration and adaptation for the cultural and contextual settings in which they are implemented.
- Relationship-centered measurement and accountability are essential. Existing pediatric health, public health, and early care and education metrics often fall short with respect to relational quality. Additional tools are needed to provide validated, culturally informed pathways to assessing and strengthening early relational health at a system level.
- Early relational health is a public good with intergenerational returns. Investing in early relational health through early childhood systems yields returns for both individual children and their families and society (e.g., increased school readiness, reduced health expenditures, stronger workforce participation). Benefits often accrue over decades and across generations (see, e.g., García et al., 2020; Reynolds-Salmon et al., 2024).
GENERATIONAL AND CULTURAL ROOTS OF THE EARLY RELATIONAL HEALTH FRAMEWORK
The committee took a broad view of the roots of early relational health as encompassing knowledge from a variety of scientific disciplines and lived experiences across cultures and perspectives in response to its Statement of Task. In so doing, the committee was inspired by the Māori metaphor of a braided river for bringing together diverse worldviews and research paradigms (Martel et al., 2022). The committee was also inspired by Indigenous perspectives within the United States and globally that understand relationships as the foundation for thriving children, families, and communities (Cajete, 2017; Day et al., 2014; Red Horse, 1997; Ullrich, 2019). The African philosophy of Ubuntu (Mathabane, 2018; Ramose, 1999), for example, offers a relational perspective on well-being grounded in the African proverb, “I am because we are.” Ubuntu recognizes that children's flourishing reflects a collective investment of families and communities, and, when relational challenges emerge, communities can provide relational support, repair, healing, and strengthening support systems. Value systems such as educación and being acomedida/o in many Mexican, Central American, and South American communities offer another example where interrelationships and mutual responsibility across generations and integration in community life are emphasized (Alcalá et al., 2018; Coppens et al., 2014; López-Fraire et al., 2024; Rogoff & Coppens, 2024).
These perspectives, and those further illustrated in Box 1-3, reinforced the committee's understanding that the development of early relational health cannot be separated from the health of the community and relational ecosystem3 in which children grow. This orientation supports early relational health by creating conditions where children experience themselves as valued members of caring communities and relational networks that extend beyond the dyad or nuclear family, fostering the security, belonging, and sense of self needed for development. It is important to note that although there are important differences among Indigenous communities in the United States and globally, there are also some principles that are often held in common. Furthermore, the peoples of the United States, and most countries worldwide, include people whose ancestry and cultural history came from Indigenous communities in other parts of the world. The diasporic communities in the United States and globally maintain many of the values and practices of the communities of their ancestors, at the same time that they often become fluent in the ways of life of their new location.

Indigenous Worldviews on Early Relational Health.
EARLY RELATIONAL HEALTH: BENEFITS TO SOCIETY
The Surgeon General's 2023 report declaring an epidemic of loneliness and a similar 2020 report from the National Academies, Social Isolation and Loneliness in Older Adults, both underscore that social connection is a fundamental human need with measurable impacts across health, education, and economic outcomes (NASEM, 2020; U.S. Department of Health and Human Services, Office of the Surgeon General, 2023). They also emphasize that social disconnection is not just an individual problem but a societal one, shaped by structural and cultural factors, including the autonomy mindset, technology, declining community participation, and shifting demographics. The COVID-19 pandemic intensified these forces, further isolating individuals and weakening social bonds across generations. The ubiquity of digital environments is also reshaping human connection and, in many cases, disrupting relational development (Haidt, 2024).
What is often underemphasized, however, is that one of the drivers of relational health in adulthood is childhood experiences of early relational health. These early experiences shape the developing brain and stress response systems in ways that influence how individuals relate to others, form attachments, and navigate emotional landscapes throughout life. The early sensitive period for development of relational processes (see, for example, Shonkoff, 2016) suggests that there is an urgency to promoting early relational health for every child, family, and community, so that children—and by extension, the adults they will become—can flourish.
NASEM (2024a) argues that
ensuring that every child is healthy, ready to learn, and on their optimal trajectory to adulthood is imperative for the nation. This imperative arises from the inherent value of child health, their future health as adults, parent and societal health, and intergenerational health. (pp. 38–39)
That report described the multigenerational antecedents of child growth and development and the impact of child health and well-being on other generations:
- 1.
It is a national value and moral imperative to give all children a healthy start in life. The future depends on nurturing young minds and bodies.
- 2.
Child health and wellbeing support the nation's tax base, workforce, economic prosperity, and sustain a high standard of living. The current young adult workforce does not meet national economic and security needs.
- 3.
Children who are sick prevent parents from working, playing, resting, and being their full selves. Parent health, happiness, and productivity depend on child health and wellbeing.
- 4.
Child health is the foundation for adult health. Most adult health problems, including heart disease, diabetes, and mental health, have origins in childhood, and the most effective prevention starts early in life.
- 5.
Scientific and technologic advancement point to the promise of earlier identification and prevention of disease to improve societal health (e.g., genomics, artificial intelligence prediction). Identification, prevention, and health promotion in the preconception, prenatal, childhood, and adolescent stages pay off. (NASEM, 2024a, pp. 39–45)
In this context, the committee for this study emphasizes that promoting early relational health can shape lifelong health. Early relational health benefits young children directly and is foundational for individual wellbeing. It also has the potential to support positive educational outcomes and kindergarten readiness, workforce readiness, community safety, and health, thus benefiting national strength, economic stability, and societal cohesion. That said, there is still much more to learn about early relational health and life course health, well-being, and societal contributions (see Chapter 6).
ORGANIZATION OF THE REPORT
This report is organized into six chapters. Following this introduction, Chapter 2 summarizes what is known about the link between early relational health and long-term health and well-being (Statement of Task questions 1 and 2). Chapter 3 describes the many influences on early relational health at the individual, relational, and systems levels (Statement of Task question 3). Next, Chapter 4 reviews promising approaches for applying the research on early relational health, emphasizing findings about the key role of family leadership in supporting early relational health (Statement of Task questions 4 and 5). Chapter 5 outlines policy and practice opportunities for advancing early relational health (Statement of Task questions 5 and 6). Finally, Chapter 6 outlines an agenda for future research. The appendix contains biographical sketches of the committee members and staff.

Flourishing is a concept that originated in Aristotle's discussions of what it means to “do and live well,” and it is embraced in social science and other literatures (see, e.g., Keyes, 2002, p. 210). According to VanderWeele (2017), “Human well-being or flourishing consists in a much broader range of states and outcomes, certainly including mental and physical health, but also encompassing happiness and life satisfaction, meaning and purpose, character and virtue, and close social relationships” (p. 8148). VanderWeele (2017) also noted the importance of sufficient stability and financial resources for flourishing to continue (p. 8149).
