Correct immediately
When a child swears, we should remind him in time and tell him, "This sentence is rude and should not be said."
Obvious consequences
Explain to your child the possible negative consequences of swearing, such as parents' disappointment, teachers' ceasing to send reward stickers, and even making people around you feel that your child is uneducated.
Teach alternative expressions
Teach children how to express themselves in a more appropriate way and show them. Tell them that other adults also express this way, and we can guide them to observe and learn.
repeatedly emphasize
We can't expect to solve the children's problems at once. Use repetitive methods to let children gradually form psychological hints, thus correcting bad habits.
