It is actually your right and responsibility as a parent to train your child. You want to discipline or train your child so they will become decent people that are nice to be around. There is a saying that if you train up a children when they are young, when they are old they will not depart from it. In other words, if you instruct and direct the growth of your children when they can be moulded they will grow up and be stable in their ways.
You see it is much easier to direct the growth of a young tree or vine. We bought a weeping willow tree for our garden one year. We had to put two strong stakes on either side of the tree to keep it from blowing over. But once the tree had roots and became stable the stakes were no longer necessary. It is the same idea with children. You need to train them in appropriate behaviour, in a way that at the end of their time with you their training will be internalized. Then they will be people you like to be around as well as contributors to society.
The thing is, a child like a tree, does not become trained in a week. It takes consistency from you to impart the character you are looking to achieve in their lives. As the parent you have the power to train up your child and if you do you will be proud of the results.
