For parents & families Essential for Living: A Special Edition

A little manual of science and practice for children and adults with very limited skill repertoires — written so that parents, grandparents and extended family can read it, use it, and share it with the teachers and therapists working alongside them.

  • New guiding lights: everyday living skills, quality of life, and the size of your child's audience
  • The first two skills to teach and the first issue to resolve, so everyday activities happen without problem behavior
  • A simple four-colour procedure for selecting an Alternative Method of Speaking that is likely to last a lifetime
