Jаke, а 20-mоnth-оld bоy, wаs referred to your clinic for a speech and language evaluation due to parental concerns regarding his language development. Jake was born full-term after a healthy pregnancy and unremarkable labor and delivery weighing 7lbs 10oz. According to the parental report, Jake has been a healthy child with the exception of two ear infections that resolved with antibiotics. He sat independently at 6 months, crawled at 8 months and began walking at 11 months of age. His parents reported that Jake babbled when he was a baby, but that his babbling and vocalizations decreased around a year of age. Jake said “dada” around 14 months but does not say any other words at this time. His parents report that, on occasion, he will lead them to things that he wants and he sometimes pushes things away that he does not want. He does not often initiate interactions or respond to simple requests made by his parents (e.g., "come here", "get your shoes"). Jake enjoys watching videos, lining up his blocks, and pushing buttons on some of his toys that make noise. There is no family history of speech, language or developmental delays.
