The onset of stuttering in two- and three-year-old children: a preliminary report.

Data on the onset of stuttering in 22 children 2 and 3 years of age were obtained through systematic parent interviews using a coded questionnaire. All children were reported to have begun stuttering prior to 36 months of age. The results indicated more similar sex distribution and greater diversity in manner of onset than was reported in past investigations. Most parents perceived early stuttering to be associated with some degree of tensions and force. The length of syllable and word repetition as reported appeared to be above the average for normally disfluent children of similar ages. Directions for future research of early childhood stuttering and clinical implications of the data are discussed.
