A selection of short stories
When a child makes a mistake, try to tell him a carefully chosen story before going to bed. The protagonist of the story can be a cartoon character or animal that children like, and describe the bad consequences caused by not admitting mistakes.
Subtle effect
As long as the story is well told, it will have a subtle effect every time, which is more effective than simple blame. Children will unconsciously accept correct values and codes of conduct.
Mom and dad cooperate.
Another way is for parents to cooperate, one does not admit mistakes, and the other criticizes to guide children to correct mistakes. In this way, the next time a child makes a mistake, it is easy to take out positive teaching materials to remind him.
More wisdom and less blame.
Educating children needs patience, more wisdom and less blame, and the effect will be better!
