Developmental Dysfluency or "normal dysfluency" is the disruption of the ongoing flow of a child's speech patterns during the ages of about 3 to 4 years old. Dysfluency refers to the broken up nature of outgoing speech and can be characterized by long pauses or the insertion of filler words. Developmental dysfluency is a normal part of the acquisition of language. An individual may not be fluent because they are a stutterer or as a result of neurogenic dysfunction but developmental dysfluency is normal in children as they work to acquire language skills and semantic/syntactic processing.
