reason things out
After they do something wrong, parents can't correct their behavior as strongly as they did when they were children. They should learn to respect them and reason with them patiently, which is acceptable to them.
Establish rules
If you want your baby to have correct values and outlook on life in the future, you need to make rules for them to do things from an early age. Let them know that these red lines are absolutely untouchable.
Deep communication
Parents should habitually talk to them more, understand their thoughts on people and things, and correct incorrect thoughts in time.
