Pediatrics spans the first 2 decades of life and is a dynamic period with rapid changes in size and physical ability, cognitive development, behavior, and nutrient needs. Registered dietitian nutritionists (RDNs) who work with the pediatric population provide the nutrition knowledge and support needed to promote optimal health and nutrition during this time across a variety of settings. The Pediatric Nutrition Practice Group, along with the Academy of Nutrition and Dietetics Quality Management Committee, have updated the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs working with pediatric populations.
