This paper addresses the challenges and benefits of involving biological parents in group homes in Israel and presents various means to encourage their involvement in care. Using family systems theories and the concept of co‐parenting, it analyses the fragile and complex relationship caseworkers and foster parents have with biological parents. The paper presents four components that might play a role in encouraging parental involvement to benefit their children's adjustment. The components are demonstrated through case studies and include assessing the family profile; addressing the family's needs within the child's intervention plan; training biological and foster parents; and building co‐parenting between biological and foster parents.
