Researchers from The University of Melbourne, Murdoch Childrens Research Institute and The University of Sydney studied over 1,600 children, following them from infancy to four years old.
They found the cumulative incidence of stuttering in Australia by four years old was 11 per cent, more than twice what has previously been reported.
However, the study refutes the long held view that suggests developmental stuttering is associated with a range of poorer outcomes in the preschool period.
Interestingly, the study found the reverse was true, with stuttering associated with better language development, non-verbal skills with no identifiable effect on the child's mental health or temperament at four years old.

Lead researcher, Professor Sheena Reilly said parents could be happy in knowing that they can take a 'watch and wait' approach to their child's stuttering and it won't be causing harm to their child's language skills or social and emotional development.
"Current best practice recommends waiting for 12 months before commencing treatment, unless the child is distressed, there is parental concern, or the child becomes reluctant to communicate. It may be that for many children treatment could be deferred slightly further," she said.
