Quick answer
What is Stammering?
Stammering (also called stuttering) is a speech difference in which the normal flow of speech is interrupted. This can show as repeating sounds, syllables or words ("b-b-ball"), prolonging sounds ("ssssnake"), or "blocks" where the person is stuck and no sound comes out, sometimes with visible effort or tension.
- How it is treated: Support is available and effective, and early input for young children is helpful.
- Self-care: Listening patiently and giving the person time (not finishing their words or rushing them), a calm, unpressured communication environment, and supportive attitudes all help.
- When to seek help: See a GP or refer to a speech and language therapist if a child starts to stammer (especially if it persists for a few months, worsens, or the child is struggling or distressed), or for support at any age.
What it is
Stammering (also called stuttering) is a speech difference in which the normal flow of speech is interrupted. This can show as repeating sounds, syllables or words ("b-b-ball"), prolonging sounds ("ssssnake"), or "blocks" where the person is stuck and no sound comes out, sometimes with visible effort or tension. It commonly begins in early childhood, often between about two and five, as children are rapidly developing language — and, importantly, many young children who start to stammer at this age will grow out of it naturally. In some, however, stammering persists into later childhood and adulthood. It is not caused by anything the parents did, and it is not a sign of low intelligence — people who stammer have the full range of abilities. Stammering can vary a lot from day to day and situation to situation, and can affect confidence and communication, so support and understanding are valuable. It is a difference in how speech is produced, not an illness.
How it is treated
Support is available and effective, and early input for young children is helpful. For a young child who starts to stammer, a speech and language therapist can assess whether support is needed and guide parents, as many children benefit from early advice and some go on to have therapy; because many young children grow out of it, monitoring with support is sometimes appropriate. Speech and language therapy is the main approach, tailored to the age and the individual — for children this often involves working with the parents and creating a supportive communication environment, and for older children and adults it focuses on techniques to manage speech and, importantly, confidence and communication. There is no single "cure", and the aim is often to help the person communicate confidently and reduce any impact on their life, rather than necessarily to eliminate all stammering. Supportive attitudes — listening patiently, not finishing words, and giving the person time — help a great deal. The reassuring message is that stammering is a common speech difference, not a sign of low ability, that many young children grow out of, and that speech and language therapy and support can help at any age.
