Raising and educating children is considered the most complex and demanding human activity. The end result is the influence of many factors, two of which are the most important - the family and the educational institution. The family is the foundation from where the growth and development of every child begins. It is the place where the first steps of learning similarities and differences, understanding and forgiveness, helping and empathy begin. An educational institution is a place where a child sometimes spends more time than in the family. For this reason, these two parties, the family and the kindergarten, are not enemies but collaborators. They are directed to joint action, which should result in a well-behaved child. In order for joint action to make sense, trust, openness, tolerance, good communication are needed, and above all, the same direction of view - the well-being of the child. This paper will describe what cooperation actually is and what obstacles it faces. The most common traditional forms, those that have been represented in kindergartens since time immemorial, and modern forms of cooperation that have appeared during the last two decades will be listed. Despite the good will of both parties, sometimes cooperation finds itself on "thin legs", i.e. in front of obstacles that can be overcome with enough effort, work and understanding. But sometimes the participants see them as unsolvable. This leads to the collapse of a beautifully built relationship, and thus to damage that is reflected in children's development and success. A positive attitude towards yourself and your colleagues is an important prerequisite for joint action. The goal of the paper is to present possible forms of cooperation, among which they are more or less focused on the active involvement of parents in the work of the educational institution. The more forms are represented in the institution for the upbringing and education of children, the greater the probability that the parent will replace his passive role with active and direct action with the aim of the best upbringing and education of his own child.
