A normal child has dysfluency of speech between:
**Core Concept**
Dysfluency of speech, also known as stuttering, is a speech disorder characterized by interruptions in the normal flow of speech, often involving repetition, prolongation, or blockage of sounds or words. It can be a normal part of child development, but persistent dysfluency beyond a certain age may indicate a need for evaluation and intervention.
**Why the Correct Answer is Right**
In normal children, stuttering typically peaks between 2-3 years of age and resolves on its own by around 5 years of age. This is because, during this period, children are rapidly developing their language skills and are still learning to coordinate the motor movements involved in speaking. As they mature and their speech patterns become more established, the dysfluency usually decreases.
**Why Each Wrong Option is Incorrect**
* **Option A:** This is incorrect because the peak age for stuttering in children is typically later than the first year of life.
* **Option B:** This is incorrect because stuttering is not a normal part of language development in infants.
* **Option D:** This is incorrect because stuttering is not typically a characteristic of speech in adults, although it can persist into adulthood in some cases.
**Clinical Pearl / High-Yield Fact**
It's essential to distinguish between normal dysfluency and stuttering, as the latter may require speech therapy or other interventions to address underlying issues. If you suspect a child has persistent stuttering, it's crucial to consult with a pediatrician or a speech-language pathologist for guidance.
**Correct Answer: C. 2-3 years of age**
