Abstract: The rehabilitation of children with disabilities should be initiated as early as possible, as soon as problems or disorders are diagnosed in the development, to prevent or promptly counteract the consolidation of disability. In Italy the institutes involved in the rehabilitation of children with serious disability must be by law highly specialized. The devices have a key part in rehabilitation courses in developmental age. They are often planned and designed in the same rehabilitation center. "La Nostra Famiglia" has been in Italy one of the first specialized rehabilitation centers for children and adolescents. By "La Nostra Famiglia" have been designed aids for children which later became a model throughout Europe. Our National Health System provides free aids for children and adolescents and describes in detail the characteristics of great adaptability that aids for children and adolescents should have. The "pressure mapping" allows you to test the effects of adapted aids versus aids not properly adapted to the size and needs.

Key words: children, early development, prevention, free aids for children, adaptability
