There is no one cause of stuttering. Possible causes include:

• Family history
  Stuttering tends to run in the family. It can result from inherited (genetic) abnormalities.

• Difficulties in speech motor control
  Research has shown that difficulties in speech motor control, such as timing, sensory and motor coordination, may contribute to stuttering.

• Other illnesses
  Examples include stroke, traumatic brain injury, or other brain disorders.

It is not caused by nervousness, copying others, poor parenting, or an intellectual disorder.

Some factors may indicate that your child is more at risk of stuttering. Knowing these factors will help you decide whether your child needs to see a speech therapist. These factors include:

• A family history of stuttering in a parent, sibling or other family members
• Stuttering at age 2 years old or later
• Stuttering persists for 6 to 12 months or longer
• Gender (boys are more likely to stutter)
• Difficulties in speech and language

A child may stutter for a few weeks or several months, and the stuttering may come and go. Most children who begin stuttering before the age of 5 often stop stuttering without any need for intervention. Consult your developmental paediatrician if the stuttering:

• Lasts more than 6 months
• Occurs with other speech or language problems
• Occurs with muscle tightening or visible struggles to speak
• Affects the child’s ability to effectively communicate at school or in social interactions
• Causes anxiety or emotional problems such as fear or avoidance of situations where speaking is required

To help your child speak more smoothly:

• Allow talking to be fun and enjoyable.
• Avoid corrections or criticisms such as “slow down,” “take your time,” or “take a deep breath.” These comments, while well-intentioned, may make your child feel more self-conscious.
• Do not tell your child to think before speaking.
• Speak slowly and clearly when talking to your child, or with others in his or her presence. Modeling a slow rate of speech will help with your child’s fluency.
• Maintain eye contact and show that you are interested in what your child is saying. Try not to look away or show signs of being upset.
• Let your child speak for himself or herself and to finish thoughts and sentences.
• Interact with your child who stutters just as you would if he or she did not stutter.
