When developing nutritional care plans for children with DD, Registered Dietitian Nutritionists (RDNs) look to authoritative guidance from the Academy of Nutrition and Dietetics to estimate energy requirements and achieve appropriate energy balance. The “Pocket Guide for Children with Special Health Care Needs” is published by the Academy of Nutrition and Dietetics, and serves as a reference for RDNs when determining nutritional needs of children with medical issues including DD.
