Impaired health
Staying up late and watching TV for a long time will cause serious damage to your health and vision. For children, this punishment has a more significant impact on their health.
Destroy parent-child relationship
Punishing children for watching TV all night will destroy the harmony of parent-child relationship. Children may feel tired and depressed, and then alienate their parents, which will undoubtedly affect the educational effect of parents on their children.
Can't achieve the expected effect
This kind of punishment can't achieve the purpose of education. The purpose of education is to guide children to recognize mistakes and correct them, rather than simply punishing them. Watching TV all night will not only make children realize their mistakes, but also make them feel disgusted psychologically, thus hindering their growth and progress.
