If you want to see a private therapist, they are listed under Speech Pathologists in the Yellow Pages. This will help you learn the best way to help your child. Treatment for these difficulties focuses on teaching individual sounds and errors. These are rule based sound errors which affect related groups of sounds. For example, a common error is called 'fronting', where the back sounds 'k' and 'g' are produced at the front of the mouth as 't' and 'd'.
Therapy focuses on groups of sounds and error patterns - helping children learn the rules.
The result is inconsistent sound errors and errors which increase as the words and sentences get longer. Therapy focuses on stabilising sound production, a great deal of practise is necessary and therapy may progress at a slower pace. Below is a list of questions to ask yourself about your child's comprehension. These provide a simple framework to think about all the many factors involved in understanding. A parent's informal observations can be very useful.
