If your child has started to stutter, you may have noticed that it does not always sound the same from one day to the next. Some bumps are quick repeats, others stretch on, and some leave your child stuck with their mouth open. At our Balmain clinic, we group these patterns into recognisable types, because knowing what you are hearing helps us choose the right kind of support and gives parents a clearer story to take home.
Developmental stuttering: the most common form
Developmental stuttering is the type we see almost every day in the clinic. It usually shows up between the ages of two and five, when language is growing faster than the speech motor system can keep up. Your child’s vocabulary is racing ahead, and the lips, tongue, and breath are still learning to coordinate at speed.
This type can come on suddenly, sometimes overnight, or build up slowly over a few weeks. Many children move through a short patch of bumpy speech and recover on their own. Others continue to stutter without early support, which is why we tend to recommend an assessment rather than a wait-and-see approach once the stutter has been around for a few months.
Less common types: neurogenic and psychogenic stuttering
Two other types exist, but they are rare in young children. Neurogenic stuttering follows an event that affects the brain, such as a head injury or a stroke. The signal between the brain and the muscles of speech is disrupted, and the resulting fluency pattern often looks different from a developmental stutter, which is why we always take a careful developmental and medical history when a stutter appears outside the usual age range.
Psychogenic stuttering is rarer again and can follow significant emotional trauma. We mention these here so you have the full picture, but if your preschooler has begun to stutter, developmental stuttering is by far the most likely explanation.
The three core disfluency patterns we listen for
When we assess fluency, we listen carefully for three patterns that make up the visible side of stuttering. Most children show one or more of these.
Repetitions
Repetitions are the pattern parents notice first. Your child might repeat a single sound (“b-b-b-ball”), a syllable (“wa-wa-water”), a whole word (“can, can, can I?”), or a short phrase (“I want, I want, I want”). In our assessments, sound and syllable repetitions tend to carry more clinical weight than whole-word or phrase repetitions, because they suggest the speech motor system is genuinely getting stuck rather than the child simply gathering their thoughts.
Prolongations
A prolongation is when a sound is held longer than it should be, like “sssssnake” or “mmmmummy”. You can sometimes hear tension building in your child’s voice as the sound stretches out. Prolongations are a stronger indicator of true stuttering than whole-word repetitions, and the moments we count them tell us a lot about how the stutter is tracking over time.
Blocks
Blocks are the pattern parents often find hardest to watch. Your child opens their mouth to speak, but no sound comes out for a moment. Their face may look tense, and they may seem to be pushing to release the word. In our clinical experience, blocks tend to appear once a stutter has been around for a while, and they often suggest the child has started to anticipate difficult words.
Secondary behaviours that often appear alongside
As stuttering develops, some children begin to show what we call secondary behaviours. These can include rapid eye blinking, head jerks, jaw tightening, lip trembling, or unusual facial expressions during a moment of stuttering. Some children also start to avoid certain words, swap them for easier ones, or pull back from speaking situations they once enjoyed.
When we see secondary behaviours during an assessment, we know the stutter is becoming effortful for the child, and that is one of the clearest signs that an early intervention plan is worth starting rather than waiting longer.
Why does the type matter when we plan treatment
The pattern of stuttering shapes the treatment plan. For preschoolers with developmental stuttering, our team usually recommends stuttering therapy using the Lidcombe Program, which was developed in Sydney and remains the evidence-based gold standard for this age group.
For school-aged children who are starting to show secondary behaviours, we may bring in speech-restructuring approaches or syllable-timed speech, depending on what we hear during the assessment.
Identifying the type is not a labelling exercise. It is the step that lets us match the right program to your child rather than guessing.
