Does your child show good understanding of language, but have a hard time getting their words out or putting words together?  Childhood apraxia of speech (CAS) is a motor speech disorder that impacts a child's ability to speak. Due to deficits in their motor planning system, children with apraxia of speech have difficulty learning or carrying out the complex sequenced movements of their articulators (tongue, lips, and jaw) that are necessary for intelligible speech.  Children with CAS often demonstrate limited babbling, however, not all children with limited babbling are diagnosed with CAS.
