If you and your husband are being understanding and supportive, you are doing what you need to do. Your daughter needs your support through this stage in her life. Since everything else seems to her to be changing from day to day, she especially needs to know that you are there for her and that you will respond to her consistently.
If you begin to believe that your daughter's behaviors and her self-esteem issues are becoming excessive, you may want to seek counseling for her. Talk with the school counselor or your pediatrician for a referral to a therapist in your community.
