Teach them not to blame someone else. Do something nice for your child when they least expect it. Have your child set some goals for themselves each year. Monitor the amount and type of TV your child watches. Listen to their music or check it out.
Some music is as bad as movies.
Have your children help plan menus for a week and then go grocery shopping with you. Set up a budget. They can help cook it, too. Get your child interested in something besides watching TV, especially in the summer. DO NOT under any circumstances call your child names or belittle them.
