Children aged six or seven are usually in the stage of child development, and there are relatively few rebellious behaviors at this age. However, if you observe that your child shows serious rebellious behavior, you can consider the following methods to deal with it:

1. Ensure that children's basic needs are met, including good nutrition, adequate sleep and proper rest time. Physical and emotional satisfaction helps to reduce rebellious behavior.

2. Establish a solid work and rest rule: formulate a stable work and rest rule, including fixed work and rest time, diet plan and housework tasks. Regular life can provide children with a sense of security and structure and reduce the possibility of rebellion.

3. Set clear rules and boundaries: Set clear rules and boundaries with children to ensure that they understand the importance and consequences of these rules. The rules should be reasonable and feasible and adapt to the children's development stage.

4. Use positive incentives and rewards: encourage children's positive behavior and use the reward system to improve their enthusiasm. Positive incentives and rewards can encourage children to adapt to rules and expectations.

5. Provide safe emotional support: express concern and understanding for children and give them emotional support and a sense of security. Pay attention to their feelings and try to understand their views. Respond to their emotional expressions with love and patience.

6. Cultivate school-age hobbies: Encourage children to participate in activities that suit their interests and abilities, such as sports, art or music. These activities can provide useful communication and development channels and help them to actively survive the rebellious period.

If children's rebellious behavior is found to be persistent and serious, which has a negative impact on children and families, it is recommended to consult professional children's mental health professionals. They can evaluate and provide appropriate treatment advice and support.
