This paper offers a discussion of the literature of an under-developed area of early years research--the exploration of childminding or home-based childcare and the contribution which this form of provision makes for children and families. Despite growing interest in childminding at the policy level and some international research on understanding home-based childcare settings and practices, there remains a relative dearth of studies conceptualising and reviewing the extant literature. This paper addresses this gap by presenting the findings of a comprehensive database search for literature and a review of published international work from 1990 to 2013. It offers a conceptual analysis of the notion of "home-based childcare", with a focus on understanding caregivers' practices, and the key issues and debates that characterise the field. The paper argues that home-based childcare not only offers a specialist type of service as family support, especially for vulnerable families, but that it provides a form of pedagogical approach to children's developmental and educational outcomes that is distinct from any other types of early years care.
