The child lied, it depends on what he lied. As long as it is not serious, there is no need to poke it.
Guiding method
You should try to guide. When he lies, you should tell according to the content of his lies. By the way, it should not be praised that he is an obedient child.
Game lies
For example. Your child has gone to play games. Just say that you recently heard that some children play games, their grades have dropped, they have been scolded by their families, and they have been criticized by teachers ... Seriously, then my children are still very obedient.
Praise the child.
Remember, a good boy is bragging. Don't praise your children reluctantly. Children have high self-esteem.
