The spontaneous verbal output of 33 2-year-old children was analyzed to identify disfluencies. The results showed large individual variability and no significant sex differences. A substantial number of children were disfluent only infrequently. Certain disfluency types not reported in previous studies of 2-year-olds were exhibited by the children. The most prominent disfluency element was repetition of short segments, one syllable or less.
