Everyone would like their children to be held up as an example to others, but to do this they will have to invest a lot of energy and resources into the upbringing process.
One of the criteria of a well-behaved child is politeness.
If you do not watch your behavior in front of your children, it is difficult to expect that they will grow up cultured and well-mannered. Therefore, "showdowns" should be conducted alone with your spouse.
Some parents don't deal with culture and ethics at all until a certain age, and then suddenly come to their children with a list of strict rules and requirements. It doesn't work that way.
So raise important educational issues from an early age.
Experts remind us that in almost all cases children take their parents as their primary model of behavior. Behave the way you want your children to behave.
That is why polite children grow up in families of cultured and educated parents.
