Much of the policy-and practice-focused research on infant-toddler care and education has been concerned with the issue of program quality. That is, what elements constitute a quality program for infants and toddlers that ensures their ongoing developmental success? Researchers have sought to identify the structural and process indicators necessary for young children to receive the kinds of responsive interactions that contribute to positive developmental outcomes. Paradoxically, while a lot is known about what constitutes high-quality care and education for infants and toddlers, most policies ignore the research by regulating a bare minimum of requirements for programs. This situation has resulted in significant variation in what infant-toddler programming looks like, where it is located, and who gets access to high-quality programs. This special themed issue of the "Occasional Paper Series" seeks to highlight and challenge assumptions about infant-toddler care and education. All the pieces in the issue can be grouped around two main themes: (1) the centrality of relationship-based care; and (2) the tensions between local/contextual and larger-scale systems-level approaches. The papers call to everyone in the early education field to advocate forcefully for infant-toddler education, for the communities in which it takes place, and for the workforce that facilitates children's development and family members' ability to work outside the home. This collection offers a vision of new pathways and resources that the field might utilize to address the under-resourcing and inadequate attention given to policy and practice addressing the zero to three space.
