This popular casebook contains new cases and materials that capture changes in child advocacy and juvenile justice. The book continues its interdisciplinary emphasis, practical approach, and in-depth coverage of lawyering, the parent-child relationship, child abuse and neglect, foster care, adoption, and juvenile delinquency, as well as the regulation of children's conduct, financial relationships, and medical decision-making. The breadth of coverage enables flexible approaches to the course. The new edition connects foundational law and concepts with contemporary issues (e.g., social media) and recent relevant Supreme Court case law. It expands the international law discussion, providing important comparative perspectives that encourage students to reflect on US law and practice. It also builds out the materials on children's agency and child development science, as well as providing additional coverage on the changing landscape of sentencing in delinquency law including restorative justice approaches. Notes and Problems (including ones drawn from the national headlines) orient students and provide background for vibrant classroom discussion.
