The aim of this paper is to show the importance of educators and parents in the development of a child with disabilities, emphasizing their competencies and cooperation without which no major progress can be expected. The role of an educational institution in working with children with disabilities encompasses a wide and diverse range of activities and processes aimed at developing the child's abilities. In order to approach children with disabilities as correctly and professionally as possible, it is first of all necessary to be properly educated. The educator as the "second mother" and the first person responsible for the child has a important role in his daily spending time in kindergarten. The education of educators, parents, their competencies and the knowledge they improve and use in working with children with disabilities are of great importance. By working with children with disabilities, the educator seeks to encourage both the emotional and social development of children. As the importance of educators is visible, so are parents who, through their perseverance, encourage children with difficulties to achieve new goals.
