In a world where all former values, like acceptance and respect, especially of risk groups, are being lost, it is extremely important to find a way to protect the most sensitive group. These are the children. It is even more tempting if a child is ill. In a modern world, chronic illnesses have become common. Even though chronic illnesses are more common in adults, the prevalence of chronic illnesses in children has been rising. The children dealing with chronic illnesses experience a great amount of stress. They deal with stress daily and fight to adjust to society due to their differences. They also experience stress during the diagnosis, while going through different invasive and less invasive diagnostic methods which sometimes cannot be avoided, and during hospitalisation and being apart from parents and close ones. Beside all that, the outcome of the illness is uncertain since the development of the illness is often unknown. Therefore, the professional and educational support, while including the children with chronic illness, is extremely important. An individual approach and planning adequate work methods is also very important. It is crucial that the pre-school teachers possess the adequate knowledge and skills connected with chronic illnesses and interventions since, often, they are the first who must react in case of complications. Regardless of the type of chronic illness the child is entitled to be included in kindergarten regular programs. Pre-school teachers present a behaviour model which encourages a social interaction with peers. The preschool teacher collects information from parents and professional associates in order to compose an individualised work program according to children needs. Depression is a common complication with chronic illnesses. A precondition for a child to face a chronic illness is strong confidence and self-respect. That is the best way for a child to manage within the environment more successfully and accept the illness more easily. It is equally important to include a child with chronic illness successfully and to educate peers in the child’s environment. Besides the professional support in educational system the support of parents and family is also important to a child with illness.
