Pediatric Feeding and Swallowing

The scope of this page is feeding and swallowing disorders in infants, preschool children, and school-age children up to 21 years of age.

See the Pediatric Feeding and Swallowing Evidence Map for summaries of the available research on this topic.

Feeding and Swallowing

Feeding is the process involving any aspect of eating or drinking, including gathering and preparing food and liquid for intake, sucking or chewing, and swallowing (Arvedson & Brodsky, 2002). Feeding provides children and caregivers with opportunities for communication and social experiences that form the basis for future interactions (Lefton-Greif, 2008).

Swallowing is a complex process during which saliva, liquids, and foods are transported from the mouth into the stomach while keeping the airway protected. Swallowing is commonly divided into the following four phases (Arvedson & Brodsky, 2002; Logemann, 1998):

Feeding Disorders

Feeding disorders are problems with a range of eating activities that may or may not include problems with swallowing. Pediatric feeding disorder (PFD) is “impaired oral intake that is not age-appropriate and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction” (Goday et al., 2019). PFD may be associated with oral sensory function (Goday et al., 2019) and can be characterized by one or more of the following behaviors (Arvedson, 2008):

Speech-language pathologists (SLPs) are the preferred providers of dysphagia services and are integral members of an interprofessional team to diagnose and manage feeding and swallowing disorders.

Avoidant/Restrictive Food Intake Disorder (ARFID)

According to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; American Psychiatric Association, 2016), ARFID is an eating or a feeding disturbance (e.g., apparent lack of interest in eating or in food, avoidance based on the sensory characteristics of food, concern about aversive consequences of eating), as manifested by persistent failure to meet appropriate nutritional and/or energy needs associated with one (or more) of the following:

SLPs may screen or make referrals for ARFID but do not diagnose this disorder. ARFID is distinct from PFD in that ARFID does not include children whose primary challenge is a skill deficit (e.g., dysphagia) and requires that the severity of the eating difficulty exceeds the severity usually associated with a certain condition (e.g., Down syndrome). ARFID and PFD may exist separately or concurrently.

Swallowing Disorders

Dysphagia can occur in one or more of the four phases of swallowing and can result in aspiration—the passage of food, liquid, or saliva into the trachea—and retrograde flow of food into the nasal cavity.

The long-term consequences of feeding and swallowing disorders can include

Incidence and Prevalence

Incidence refers to the number of new cases identified in a specified time period.

Prevalence refers to the number of children who are living with feeding and swallowing problems in a given time period.

It is assumed that the incidence of feeding and swallowing disorders is increasing because of the improved survival rates of children with complex and medically fragile conditions (Lefton-Greif, 2008; Lefton-Greif et al., 2006; Newman et al., 2001) and the improved longevity of persons with dysphagia that develops during childhood (Lefton-Greif et al., 2017).

Estimated reports of the incidence and prevalence of pediatric feeding and swallowing disorders vary widely due to factors including variations in the conditions and populations sampled; how pediatric feeding disorders, avoidant/restrictive food intake disorder (ARFID; please see above for further details), and/or swallowing impairment are defined; and the choice of assessment methods and measures (Arvedson, 2008; Lefton-Greif, 2008). The data below reflect this variability.

Signs and Symptoms

Disruptions in swallowing may occur in any or all phases of swallowing. Signs and symptoms vary based on the phase(s) affected and the child’s age and developmental level. They may include the following:
