Childhood Apraxia of Speech
KJ was a 3.5–year-old, nonverbal boy with reported “strong” receptive language skills and no significant family history of speech-language difficulties. Perinatal history included induction at 36 weeks due to maternal preeclampsia and a birth weight of 5.6 lb. According to parent report, KJ did not latch successfully during breastfeeding and presented with limited babbling and sound play in infancy, although developmental motor milestones were met. During his first 2 years, KJ produced occasional vowel-like productions with few attempts at consonant-vowel combinations; first words (“da” and “muh”) emerged at approximately 25 months of age but were “lost” shortly thereafter. He was reported to drool excessively until age 3. KJ demonstrated strong communicative intent and primarily communicated through leading/guiding, vocalizing, and gesturing, although he occasionally hit and bit others when frustrated. Socially, he was often withdrawn, especially with peers in preschool or with unfamiliar communication partners.
