Children go through the same learning patterns while developing their first language as adults do when learning languages other than their native language.Although many adults display types of dysfluency, it is usually in relation to comprehending or expressing different materials under stress. Developmental dysfluency is a normal part of the acquisition of language. An individual may not be fluent in language due to frequent stuttering or as a result of neurogenic dysfunction. The origin of stuttering is not yet fully understood but parents/adults can mitigate the risk of developmental dysfluency by reducing the conversational demands on their child. Modeling slow, smooth speech and acknowledging the demanding and complex nature of learning language can help. Symptoms
Symptoms of developmental dysfluency include the repetition of sounds or pauses between words. These symptoms have generally been noted within children from 18 months to 5 years of age. This may persist for weeks or months but eventually disappears due to the maturation of the childs nervous system. Children with a family history of stuttering are more likely to develop the disorder than those without.ex. : "Mommy, I am, I am, um, I am..."
Usually, this language dysfluency is a transitional stage that most children will leave behind as they master oral communications. At this point, there is little to no need for any therapeutic intervention. The typical occurrence lies between the ages of 18 months and 7 years as children pass through stages of speech dysfluency as they learn how to talk.
