What influences the child's adjustment is his age, readiness to go to kindergarten, the child's temperament and the social contacts he had until then. The impact of parents' emotions on the child is really great, especially bearing in mind that children recognize and project them very well, which can greatly complicate and prolong the process of adaptation. The cooperation of educators with parents is important: assistance in planning work, getting to know the child and in spatial and material planning of the appearance of the educational group, organizing meetings and workshops for parents, counseling, education and introducing parents to the plan and program of the educational group. This will all help the child to develop security in kindergarten and independence from the parents, and it could help the parents to cope more easily with the new role they have. Educators have a special importance in adaptation, they are qualified people who spend the most time with the child. One of the tasks of educators is to create a sense of security and mutual trust of all participants in the adaptation, all in order for the child to accept being in kindergarten. In order to achieve this as easily as possible, it would be best to ensure quality cooperation with the parents, which will tell the child that the educator is a safe and reliable person whom the parent trusts. However, educators are there for much more, they organize the context of the kindergarten according to the child's needs, offer incentives and activities, teach children and pass on their own knowledge and skills. It is very important to encourage educators to continuous education and motivate them to constant improvement through reflective practice.
