If you have a teenage child, you will have found that it is difficult to discipline him/her. This is the stage when the teens start looking for independence and identity for themselves. There are disciplinary and behavioral issues that come forth and it becomes hard to communicate with your teen.
Most important here are patience and persistence. Your teen does not have to be bound strictly by rules because that is sure to make him/her more aggressive and neither does he/she need too much supervision, because that will make him irritated and you will have to witness aggressive defiant behavior. But you do not have to do nothing.
Be nominal in your approach without being opinionated. Communication that is crisp and clear cut, with the consequences explained in brief usually will suffice. Your teen is looking for independence and any pressing behavior exhibited from your end will result in a defiant attitude or an angry response.
Following are some ways that you can adopt to deal with your teens more effectively:
The most important thing is for you to understand and acknowledge their need for space. The age that they are at, they begin to perceive the ways of the world and want to have their own identity established. Any directions given from you to help them make their decisions will be received skeptically. Therefore do not lay out a course for them, just give them options when they need them and let them choose what is best for them.
This is the time when the hormones of the teens are evident and therefore their responses are charged with emotions. Do not be detracted or disturbed by this because this is normal behavior. Your acceptance of the fact will make it easy for you to deal with them. Do not chide them for their behavior.
Give them their private space. Do not disturb them when they want to spend time alone. Try not to be critical of their appearance when they put on makeup or wear different clothes.
Make them understand that they are responsible for their actions and also be supportive. Any accomplishments must be praised; no matter how grumpy they look acknowledgment of success does make them happy. But do not go overboard.
