Positive discipline is not specifically targeted at any group, but different groups use different tools. For example, the tool "hug" is suitable for children of almost all ages, but adolescent children may refuse it, so we can use another tool to strengthen our contact with adolescent children, such as "special time". When we should respect children's choices, we should use "limited choices" for younger children and "heuristic questions" for older children.
Therefore, it is not to say that we have to face any crowd, but to choose different tools to solve different problems according to our actual situation.
