The federal government, states, and municipalities have placed the accelerated expansion of childcare for children aged zero to three at the top of the political agenda. Childcare facilities face significant challenges both organizationally and in terms of staff qualifications and the necessary educational concepts. This is because the youngest children in daycare have different needs than older children. The handbook fills a gap that has existed in the professional literature by not viewing daycare pedagogy as merely an educational topic, but rather allowing for a more comprehensive perspective. The first part of the handbook introduces the historical, political, and legal framework of daycare pedagogy. The second part focuses on early childhood educational and developmental processes and contrasts them with classical approaches from attachment research.
