The teen years are often rocky between parents and their children as a once compliant child pushes boundaries or becomes sullen and unresponsive. Teen behavioural problems are caused by factors such as hormones, peer pressure and depression or anxiety issues. It's important as a parent to recognize the signs and seek help if the problem becomes larger than you can handle. Also, remember a small problem can snowball into a larger, more complex one if not dealt with properly. One of the most common problems parents face with their teens is lying. Many times the lie is relatively small - lying about not having homework or watching an extra hour of television. Or, the lie could be more severe - not telling the truth about drug and alcohol use, or taking the parents' car when they aren't home. If you let your teen get away with smaller lies, there's a good chance they will eventually avoid the truth when it comes to more serious problems. You must remain strong when you discipline your child and not waver with a promise of never lying again. If you set boundaries for your teen, he or she will realize that to lie means suffering the consequences. Teen depression is common in young adults, although many keep it a secret from their parents. Teens face stress from a number of sources: friendship and romantic relationships, academic pressures, bullying, sexual abuse and uncertainty about the future are just some of the reasons teenagers battle feelings of depression and anxiety. By monitoring your teen and offering guidance and support, you may be able to learn more about what is causing your teen to feel depressed. There are many depression medications and therapy programs available to help your teen for things like self harm, eating disorders, and suicidal thoughts. Watch for symptoms like changes in eating and sleeping, difficulty focusing, loss of interest in activities, and increases in drug and alcohol use. Teen suicide is nothing to take lightly, and sometimes depressed teens take this route. If your teen commits a crime or is violent towards others, the situation may go beyond the parents. Today schools have zero tolerance for violence or bullying of other students, and if your teen is a repeat offender, he or she will face criminal punishment. Teen behavioural problems often mean the youth is sent to a residential teen facility. The amount of freedom varies depending on the seriousness of the crime - some teen residential facilities are voluntary, whereas others are juvenile detention centers that are a lot like adult prisons. Teen boot camp is another last resort for parents raising teens with an out of control drug or violence problem. Children are held in military-like conditions and given a strict regiment for waking, eating, sleeping and working to learn about authority and respect. Teen wilderness programs are also strictly regimented but some experts feel that teens recieve nurturing and peace from being in a natural environment.
