You did not say whether your stepchildren live with you full time or how long you have been married. I have advice for you which you may or may not like. I have been a stepmother for several years. The first thing in your letter that strikes me is that you say that you made the appointment for family counseling (which means that the girl's mom and your husband did not and may not see this as that big of a problem or maybe trying to ignore the situation in the hope that it will resolve itself.) You are correct in saying that the girls mom will likely cancel out all the good efforts you make with this in your home. This is just something that you have to anticipate will happen in your situation, that way it will not frustrate you as much if it does happen. This girl is crying out for help. Whatever you do, don't go into family counseling and focus on the 11 year old as the only problem. I suspect that there are other problems in the family which you may or may not realize are there. You should approach the family counseling as this is something we are doing to improve all of our relationships and communication with each other. I believe all of this acting out behavior with boys may be due to a need for your daughter to have what she considers as positive interaction with a male. If you have six children, it could be that she needs more one on one attention with your husband and that all this acting out is because of that. Allow and encourage her and your husband to do things one on one with each other several times per week. Let her have a chance to open up to him without you. Even though you believe her mom has a strange way of dealing with this, always encourage her to remain close to her mom, unless doing so would pose a danger to her. Never bad mouth the bio mom to her or other people, that will only ruin your relationship. Your role as a stepmom is to support your husband's decisions and not be actively involved in discipline, etc. (Not be first to discipline the stepkids...that won't work and they will only resent you for it.) Just try your best to be a supportive adult and role model of positive behavior for all your children, especially your stepchildren. Let them know that they can always come to you with any concerns. Good luck and best wishes in this situation. Your husband, the bio mom and you need to start talking with this girl about consequences of sex. It may not be a bad idea to take her for a physical and get the dr. to talk with her also about her changing body, consequences of sex, etc.
