We can learn patience. In these stories, the parents and others around the stubborn children often need to be very patient. For example, when a child is stubborn about not doing something, like in the case of the boy not going to school, people have to keep trying different methods to get through to the child.
Another lesson is the importance of communication. In the story of the girl who was stubborn about her dress, when her mother had a proper conversation with her, it started to change the situation. So we should communicate effectively with stubborn children to understand their point of view and make them understand ours.
