This assignment provides an in-depth analysis of child welfare and protection systems, covering various aspects such as policy and practice on children's exposure to domestic violence, workforce development, and the overlap of witnessing partner violence with child maltreatment. It also explores the concept of mother abuse and its relation to youth justice, child welfare, or domestic violence. The assignment draws from recent research and publications in the field, including the Munro review of child protection and the Lancet's publication on child maltreatment.
