Editing Stuttering (section)

====Developmental (and persistent)====
"Developmental stuttering" is a sometimes transient period of stuttering that has its onset in early childhood, i.e. when a child is learning to speak. About 5-7% of children are said to stutter during this period. Despite its name, the onset itself is often sudden. This type of stutter may persist after the age of 7, which is then classified as "persistent stuttering", which is the typical aetiology, pathogenesis, and presentation of adult stuttering.<ref name="gordon">{{cite journal |last1=Gordon |first1=Neil |title=Stuttering: incidence and causes |journal=Developmental Medicine & Child Neurology |date=April 2002 |volume=44 |issue=4 |pages=278–282 |doi=10.1111/j.1469-8749.2002.tb00806.x |pmid=11995897 }}</ref><ref name="craig2005">{{cite journal |last1=Craig |first1=A |last2=Tran |first2=Y |title=The epidemiology of stuttering: The need for reliable estimates of prevalence and anxiety levels over the lifespan |journal=Advances in Speech Language Pathology |date=March 2005 |volume=7 |issue=1 |pages=41–46 |doi=10.1080/14417040500055060 }}</ref><ref name="Sander and Osborne" />
