Germany is a country of immigration where people from different countries of origin come together. In some cases, they are guided by rules of behavior and values that are considered unusual or "foreign" in Germany, which often causes irritation and misunderstandings. One particularly sensitive area is educational ideas and practices that do not correspond to the pedagogical guidelines valid in Germany, which guide the actions of professionals. The articles in this series provide knowledge about the culturally diverse forms of caring for and raising children. Different family forms as well as different ideas about "good childhood", "proper upbringing" and "emotional attachment" are addressed. Knowledge about the diversity of forms of care and upbringing is absolutely necessary when dealing with families that come from other social and cultural contexts and deal with their children in a way that does not correspond to Western European middle-class ideas about "proper" child rearing. This paper examines the cultural diversity of family constellations, care systems, and attachment patterns and critically engages with psychological attachment theory, whose universal validity is questionable from a social anthropological perspective. Using diverse case studies, practices of multiple care systems are cited, suggesting that a "secure attachment" of children does not result from their relationship to one or two central caregivers, but from their firm embedding in a network of relationships. The content is aimed at professionals in the fields of social work, education, family support, and child and adolescent psychology.
