Throughout history, children with developmental disabilities did not enjoy a privileged status in society, but on the contrary, they were marginalized and often rejected. The common practice was to segregate hearing-impaired children into separate special institutions, institutes and schools in order to achieve the best possible progress in their educational process, even though this often meant separation from their parents and primary family. Such traumas have further increased social isolation and basic problems faced by hearing impaired children, such as the inability to express themselves, difficulties in communication and unavailability of information. The most noticeable consequence of hearing damage is partially developed or completely undeveloped speech. Hearing impairment also affects the psychomotor development of the child, his judgment and finding his way in the environment in which he needs to integrate. For a long time, there was a common opinion that parents are not too expert to help their child in the process of integration into society and in training for life despite difficulties in development. They were not seen as an important link in the process of rehabilitation and education of children with hearing loss until the middle of the 20th century, when experts in the fields of pedagogy, psychology, medicine and other sciences saw that the best rehabilitation is carried out in the early stages of life, i.e. from the first year of life when the child is especially attached to the mother. The family is the initial starting point for the successful development and growth of the child, and even more so if the parents are involved as part of the professional team in the rehabilitation of hearing and speech. They need to be supported and educated in order to have a positive attitude, understand their child as well as possible and soon see progress. A well-designed collaborative relationship between teachers and parents, mobile teams, teaching assistants, educational translators should contribute with their expertise and knowledge to more successful rehabilitation and integration of a child with hearing loss into society and the regular school program.
