Case analysis of children's mental health

I don't know if you are asking about the classification or specific topic of case analysis of infant psychology. Let me give three examples. 1, try to analyze the harm of the following practices from the perspective of preschool children's psychological development. Some parents are eager to "dream of success" and arrange a series of learning activities for their children, such as learning English, piano, art and so on. Every day, the study schedule is full, and Saturday and Sunday are no exception, for fear of children being playful. I never let my children play with my neighbors' children easily, and I don't want to play with them myself. Even if children want to try to do some simple housework, it is entirely arranged by their parents. 2. "A child asked: Mom, do you know what the proudest animal in the world is? Let me tell you, this is a goldfish! It always shakes its head. " Why do children come to such a conclusion? Please analyze the reasons. A teacher recorded an experience of hers. The children in the class caught the snail, but the teacher forced them to throw it, and no one would. So the teacher folded a "house" with paper, asked them to put all the snails in it, and promised them that they could take the snails home after dinner. As a result, the children ate quickly. Please analyze the method adopted by this teacher.
