This study will examine the effects of varying liquid viscosity on swallow physiology in infants with oropharyngeal dysphagia and brief resolved unexplained event (BRUE) and other children with dysphagia that would be at risk for symptoms of swallow dysfunction.
Age 0 to 21 years

Have had videofluoroscopic swallow study performed or might have future videofluoroscopic swallow study performed.
Any pre-existing medical diagnoses that exclude brief resolved unexplained event diagnosis including seizure disorders and cyanotic congenital heart disease
Any nasal/pharyngeal/esophageal anomalies that might affect safe placement of the pharyngeal motility catheter
Children fed exclusively by enteral tube
