Well-mannered kids aren't seen that often today. Children seem to be the ones in charge rather than their parents. Parents lost control over their children in many respects and that control should be brought back to where it belongs. If you want your children to be well-mannered then you have to raise them that way.
Here is how to bring up well-mannered kids:
You children need to know your expectations. Your expectations should be that your children are well-mannered. When they are behaving otherwise, you need to let them know that you are the boss and that you won't tolerate ill-manners. In order to do this, you have to make it clear to them what your expectations are in regards to good manners.
Discipline is a huge part of parenting. You must find ways to discipline your children when they exhibit poor behavior which includes ill-manners. When your kids behave in a manner unbecoming then you must discipline them if you want them to change their attitudes. Discipline is a major player in the game of parenthood. That doesn’t mean you have to beat your children. It means that you must put a plan into action so that you children know there are consequences to certain actions.
The only way that kids learn how to be well-mannered is if you teach them how. Children aren't born with good manners. They will not know how to behave properly if you don't teach them. Play games with them to teach them manners. Correct them when they do something that is ill-mannered. Above all else, be a good role model. If you aren't then you can't expect your children to be well-mannered. Teaching your children about good manners is part of the daily routine. If it isn't, then you should take steps to make sure that it becomes a part of the routine. As children grow, good manners will become a routine for them because you taught it to them every day.
These are the main ways in which you can bring your kids up to be well-mannered. It is a matter of teaching, expecting it and disciplining when they don't follow the guidelines you have set for them. You children will watch what you do as well. Be a good role model because that is the best teacher for your children's manners. Don't allow your children to run your home, you are the adult and therefore you are responsible to make sure your children follow the rules.
