For a majority of people it is a necessity to have children in their household and with it comes the responsibility of keeping them in check and getting them to behave well both in the house and around other people and guests. As such there are some things that a parent can do to raise a child that is well behaved.
The first thing that you can do as a parent to ensure that your bad behavior children are well behaved is to lead by example. This is showing your children what you want them to do and how to do it. Children learn a lot of things by just watching, and if you can show them what you expect of them, then your children will behave well. Sometimes they may be watching while you are not aware of their presence and therefore this means that you should be very careful with your actions around the house or anywhere else or the words that you utter.
The other thing you can do is to praise your kids. A lot of the times parents give more attention to the wrongs that their kids do and turn a blind eye to the good that they may have done. If you as a parent give your child more attention when he or she does something right then, he will be encouraged to keep on repeating doing the good. It inspires them to repeat the good behavior because they will be hoping to get the same treatment as before. Know about family relationships here!
Also as a parent, you need to be decisive and firm. Sometimes you will feel bad for not allowing your children to do what they want but that does not mean that you have to change your mind about it. It is necessary because some children can spot that as a weakness and they will use it as blackmail against you because they know that you will change your mind about whatever it is you did not want them to do or have.
Reward your kids when they behave nicely or when they do something to your expectations. This does not mean necessarily money, but other things like taking them out for ice cream. This way the children will know that with having good behavior comes with rewards, and they will always strive to behave well so that they may be rewarded. The best gifts can be in form of toys.
