This chapter examines the integration of professional discretion and child-centered music therapy within the framework of the United Nations Convention on the Rights of the Child (UNCRC). Child-centered music therapy prioritizes the child’s individual needs, preferences, and rights, fostering a collaborative and supportive therapeutic environment. This approach empowers children to actively participate in decision-making processes, express themselves creatively, and develop resilience. However, the UNCRC’s concept of the “best interests of the child” is critiqued for its ambiguity and potential for manipulation. The chapter underscores the necessity of professional discretion in balancing the paradoxes of dependency and independence in childhood and ensuring ethical, context-sensitive interventions. Collaborative teamwork and structural reforms are recommended to address systemic barriers and inequalities, promoting dignity, safety, and equal opportunities for all children. This research contributes to the discourse on children’s rights in music therapy, advocating for reflective, rights-based practices to enhance therapeutic outcomes
