Make firm rules for issues that really matter to you, and negotiate those that don't. Be flexible in deciding how old your daughter needs to be for her to have a say about issues that affect her, such as clothes or hairstyles. Don't hesitate to say no if the request doesn't seem right to you. As your daughter moves through the teen years, increase the degree of her responsibility. By age 16, she may be able to drive without you given that she comes home by a pre-agreed curfew.
Teenage girls are more prone to low self-esteem than boys.
Giving your daughter a strong sense of self will help her make the right choices during this confusing time. Applaud your daughter for her skills and intelligence, not just her appearance. Encourage her to take risks, such as learning new skills. Expose her to a variety of activities and interests. It's up to you to counter any negative images and information she may see.
