A photo of four children wearing orange high-visibility vests in the forest is captioned, “We look for treasures in nature and check what is hiding underneath the leaves.” Another picture shows three boys building a house out of a cardboard box. “Collaboration,” the caption reads. “Helpfulness,” says another caption, next to a photo of a boy helping a girl slice a sausage. As we sit down on the floor for fruit time, I make another observation: None of the children in the room are overweight.
