Our community includes many children with developmental disabilities who should be actively included in the process of early and preschool education. These children require proper support and support, above all from their parents, educators and their peers from educational groups. It would be ideal to provide educational and rehabilitation staff and educated people, i.e. assistants, with work in groups where there is a child with developmental difficulties. The right of every child to have their basic life needs met, including the need for movement, a sense of belonging and the possibility of active participation, is clearly stated in the Convention on the Rights of the Child. By encouraging inclusion by supporting children with developmental disabilities in physical activities, educators contribute to the realization of these rights, without being connected to a specific source. By involving children in physical activities, children's self-confidence and self-esteem are encouraged and developed, and the values of respect, responsibility, obedience and the like are promoted. It is necessary to approach children who are developing with developmental challenges in a way that will allow them to feel important and belong, instead of leaving them out or discriminating against them. As part of this research work, the presence of children with developmental disabilities during physical and health education classes in preschool institutions was verified. The paper deals with the most common types of challenges that educators face every day and presents the results of the activities of children who are developing with developmental disabilities. Furthermore, a survey was conducted with the aim of determining the number of children with developmental disabilities who participate in physical and health education classes in kindergartens throughout the Republic of Croatia.
