The two main characters, Leon and Jelena, attend kindergarten together. Here, they are allowed to participate in many aspects of daily life, such as deciding how to better organize breakfast or how to resolve the dispute over the tricycles that many children want to use at the same time. Through this, they learn a lot about how to shape a community so that everyone gets their fair share. The individual volumes vividly and child-friendly illustrate how Leon and Jelena can experience their social engagement from an early age. The five titles are: - The new climbing tower - A place for breakfast - The tricycle stop - Jelena in the children's parliament - The dog mess in the park. A place for breakfast: Leon and Jelena advocate for the children in the blue group to have a designated spot where they can always have breakfast.
