Foster children often encounter worldview differences between their foster family and their birth family, for example, when participating in religious activities and practices. Foster children not only have a right to continuity in upbringing but also consistency in worldview, culture and language. Good co-parenting relationships are important for their identity development. For these reasons, foster care workers are entrusted with the task of supporting the triadic relationship of the foster child, birth parents and foster parents in dealing with worldview differences.
