The topic of the final paper Children with osteogenesis imperfecta was chosen from intrinsic motivation for learning about that diagnosis because I had work experience with a child suffering from brittle bones. In the Croatian academic community this rare desease is insufficiently presented, and in a way of describing the functioning and need for support. Based on the above, there appeared a need to raise awareness of every crucial participant in creating and providing support with this diagnosis, about the facts that should be considered while planning and implementating support. One of the crucial participants in providing support to children with osteogenesis imperfecta is the preschool education system. Including a child in a preschool system is the first big milestone in the life of a child and the family. Because of that reason, the educators and the expert service of the kindergarden play a crucial role in providing support and including the child. Osteogenesis imperfecta is also named as brittle bone desease, and the characteristics of the bones are that they are fragile, weakened and easily breakable, so the holistic approach to a child is needed to prevent additional difficulties or damages. In this paper, the used expression will be osteogenesis imperfecta. The professional and scientific literature greatly easens choosing the adequate approach, providing the needed support and making the right decisions about an adequate didactic and methodic approach in working with children with osteogenesis imperfecta. Considering that the accessible scientific and professional literature is predominantly medical, in this paper I will give accessible information and bring the diagnosis closer to educators, in purpose of providing this group of children the adequate support of professionals.
