Twenty-five infants between the ages of 1 month and 24 months who have just been diagnosed with dysphagia via a modified barium feeding study will be recruited into the study. The infants will be sedated with chloral hydrate and have pulmonary functions measured (pre- and post-bronchodilator spirometry and lung volume) using the infant pulmonary laboratory. Treatment for the infants' dysphagia/chronic aspiration will be treated as determined by the primary care physicians. Six months later the infants will again be sedated and have pulmonary functions measured. Results of the two sets of tests will be compared statistically.
