A pediatric feeding disorder is defined by "impaired oral intake that is not age appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction" (Goday et al, 2019). Treatment of PFDs require interdisciplinary care with a child's full medical team to ensure each domain that is present is appropriately managed. Brief description of the four domains are below: 

Medical: Medical conditions that impact feeding such as cardiovascular conditions, syndromes, cleft palate, tongue tie, Autism, ADHD, constipation, gastrointestinal disease, reflux, eosinophilic esophagitis, aspiration, etc. followed by the appropriate medical provider for management. 

Nutritional: Limited diet resulting in nutritional deficiency or low volume of intake impacting the child's ability to meet their daily caloric needs. 

Feeding Skill: Difficulty biting, chewing, moving food in their mouth, and swallowing are associated with feeding skill. Additionally, core stability, self feeding, sitting safely to be able to consume food, and sensory regulation are also included in feeding skill. 

Psychosocial: Anxiety, fear, or increased stress around meal times, eating, or trying new foods. The psychosocial domain also includes the eating environment, the relationship between caregivers and children around eating, and caregiver stress around meal times.
