Sometimes you can change the use of your rooms so that there is a space for adolescents, and a space for parents and any younger children in the family. This gives the adolescents some privacy. Keep plenty of low cost food, such as bread and fruit in season. If necessary label what is to be kept for family meals and what is available for snacks. Be clear about what videos are allowed to be watched at your home and why.
Teenagers get a thrill out of watching scary videos in a group, so allow some flexibility.
If there is pressure on your teenagers to raid your alcohol, make the rules clear and explain the reasoning. Talk with your teenagers and your partner about your values on sexual activities and the behaviour you expect in your home. There are many things that you might want to take into account e.g. the age of your teenagers, the nature of the relationship, where else they would go if they were not at home, and of course your own values. Occasionally try to spend time with your teenager doing something special together. Go to a movie, watch a football game, take a walk, go for a swim.
