The last post listed the first step in preventing your rebellious child from becoming an all-out menace: NO driver's licence.
2. The second extreme step is to cut off ALL privileges: cell phone, TV, movies, anything at home or school that is not necessary for life and education. That cell phone is their private connection to a world you would never approve. Your standards dictate necessity, not theirs. A horrified teen will swear to you she HAS to have that cell phone "for work." We were fools to buy that one and should have thrown the phone in the toilet. We all managed without cell phones in the Dark Ages, and they can too. If you bought it or are paying for it, out it goes.
If he is paying for the whole thing himself, demand complete access to all texts and calls and limit his access to it (i.e. after 10 PM, the phone goes with you.) Our modern concept of a teen's "right to privacy" is laughable. I don't know what gullible adult signed on to that theory, but if you are responsible for that child, he has no rights that supersede your right to train and protect him.
6. Find a trusted adult counselor to meet regularly with your child, whether Junior likes it or not. When they are in full-scale rebellion, they don't like anything, so don't try to please them. This a counselor of your choosing and they go when you say to go. Sometimes giving them a safe place to vent helps them work through issues that don't have to be life-altering.
I wish we had paid more attention to the signs that our daughter was in trouble and gotten her to a counselor early on. But a word of caution: I would only choose a counselor who knows you and your family very well. Defiant kids are more skilled at lying and manipulating than you can imagine and a skillful con artist can paint a picture of woe that you would scarcely recognize.
