Early intervention refers to programs developed for infants and young children with developmental delays or inadequacies or who are at risk group, and their families. The aim of the early intervention is providing services for children with disabilities, minimizing their developmental delay and disability levels and guiding parents for positive development of children. Early intervention includes extremely important studies for children in need of developmental support and their families. The effective early intervention treatment requires a gradual progress, teamwork with a multidisciplinary approach, and family should be considered as the most important element of the treatment and participate in the decision-making at every phase, alongside effective use of the Individualized Family Service Plan and updating the plan when it is necessary. It should be noted that early intervention is an ongoing process. In this process, the family and the child should be considered as a whole and supported in a holistic way.
