Early Childhood Interventions offers the first book-length critical account of Global Early Childhood Development (Global ECD) interventions in the Majority World. Bringing together leading scholars across anthropology, psychology, developmental science, sociology, and social work, it asks a simple question with high-stakes consequences: whose evidence counts when “optimal” parenting is packaged as a universal recipe for national prosperity?Global ECD has moved rapidly from a set of technical programs to a powerful 'common sense understanding' of child development, crystallized in initiatives such as the WHO-UNICEF-World Bank Nurturing Care Framework, which links everyday caregiving to brain development, human capital, and long-term economic growth. Yet the volume shows how the evidence base invoked as “best available” is often narrow and uneven: anchored in urban, middle-class Euro-American research, filtered through selective reviews, and exported as a benchmark against which Majority World families are measured, too often producing deficit diagnoses rather than understanding.Across richly grounded chapters, contributors trace how Global ECD travels, what it renders visible and invisible, and what it does to families, institutions, and policy worlds. The book also offers practical tools for building a broader, more globally representative, context-attuned science, one that treats difference not as failure, but as a starting point for better research and more just interventions.
