As parents, we can set aside time to be a family, such as sitting down at dinner together everyday. We must set rules and stick to them. We cannot waver from them or show favoritism. Don't give me a 10 o'clock curfew and them not let me go out at 9 o'clock. Parents may need to organize their lives before they can help their teenage children.
Rules apply to adults as well as their children.
Don't expect respect from your children, if you don't respect them. Parents also have to remember that it is more important to have an organized life than it is to have an organized room. Be sure your children are as similar to other children as they can be. Even if you can afford six pairs of no-name jeans, but only two popular brand, buy the popular brand. This applies to shoes also, scrimp on other things.
