A foster sibling is a child who lives with a family that is not their biological family, often due to various circumstances such as neglect or abuse. In these situations, the child is placed in a foster care system, where they may be cared for by foster parents who provide a temporary home. Foster siblings can either be biological siblings placed together or unrelated children living in the same foster home. Living with foster siblings can create a unique family dynamic, as these children often share experiences and challenges related to their backgrounds. They may form strong bonds and support each other through the transition, helping to create a sense of belonging in a new environment.
