1. Communication: If the child is rebellious, it is not recommended that parents directly reprimand or strongly ask the child to complete something. Instead, they should improve their communication methods, such as patiently communicating with their children to avoid the pressure and emotions in their hearts. Through communication, you can clear your mind and get solutions to problems;

2. Learn to listen: Nine-year-old children can clearly express their ideas, but if parents are not good at listening at this time, they may have resistance, which may lead to children's reluctance to express their ideas in the future, forming a vicious circle;

3. Trust and tolerance: There will inevitably be some misunderstandings in life. Parents need to believe as much as possible that their children's nature is kind and upright, and think from their children's point of view. If children do it right, they should be fully encouraged. Nine-year-old children have poor control over their emotions, so they need more tolerance from their parents to avoid their rebellious mentality;

4. Make rules: Nine-year-old children have gradually established their own concept of judging right and wrong, and their self-awareness has begun to strengthen. Parents can start to make rules on an equal level with their children, so that children can understand the benefits of obeying the rules, which is conducive to regulating their own behavior;

5. Lead by example: Parents' behavior will affect children subtly, so try to avoid quarreling and losing your temper in front of children. Parents should keep calm when they encounter problems that cannot be solved, so as to set an example for their children.
