Abstract: Therapeutic communication is a cornerstone of effective pediatric and family-centered healthcare. Unlike adult communication, interaction with children requires sensitivity to developmental stages, emotional needs, cognitive abilities, and family dynamics. Children often lack the verbal skills to articulate their fears, pain, and concerns, making therapeutic communication both an art and a science. Families, as constant caregivers and emotional anchors, play a pivotal role in the child’s health experience, decision-making, and recovery. This review article explores the concept, principles, components, and significance of therapeutic communication with children and families. It examines developmental considerations, communication strategies across pediatric age groups, the role of nurses and healthcare professionals, barriers to effective communication, ethical and cultural considerations, and evidence-based approaches that enhance trust and therapeutic relationships. Emphasis is placed on family-centered care, emotional safety, and holistic healing. By strengthening communication skills, healthcare professionals can reduce anxiety, improve treatment adherence, enhance patient and family satisfaction, and promote better health outcomes. This review highlights the critical role of therapeutic communication as an essential clinical competency in pediatric nursing and interdisciplinary healthcare practice.
