Pre teen girls....yikes!

I've got one....one of those pre teen girls that is almost just a little bit too big for her britches! I am so struggling with finding a balance of discipline with her. She is an amazingly compassionate, and loving child. Her nature is to not hurt a fly...but I'm convinced the influences that surround our girls these days overwhelm them. Girls that are only 1o are doing things that 15 and 16 year olds used to do. If you have ever watched any episode of Suite Life of Zach and Cody...or Drake and Josh....and pay attention at all...it is disgusting the amount of disrespect and bad attitude these kids have towards any sort of authority whatsoever. I'm sure we owe pop culture a great big thank you for that...but I think it shows a pattern in parents as well. Now, don't think I'm claiming to be the best parent ever....if I was, I sure wouldn't be struggling as much with what on earth to do. What I mean by the affor mentioned statement is.....pop culture can say what it wants...but we as parents have the right and frankly the God given obligation to say no. I can't even tell you how hard that has become to a certain level. For Chandler...my oldest...he would just accept no, and move on. He may not like it, but he would for the most part, accept it. He pretty much knows now, that we just aren't going to let him go to dance parties left and right. We've let him go to 2, and they were given by the same person. We are comfortable with the parents....so it was ok. Madison on the other hand just doesn't accept no very well. She is very much her mother's child. I never have accepted no well....and I'm paying for it now. Ha! Not to make excuses, but I think girls are far more brutal than boys are in terms of peer pressure...at least for this age. Recently, there was a movie that I strongly disagreed with her going to. Again, Chandler knew I wouldn't let him...and he actually agreed that it wasn't appropriate after we read the reviews....Maddie..not so much. She stood her ground with me for awhile...but then her stance began to erode. Every other friend was going....I've let her see worse, etc. etc. And I have let her see worse...but learned from those mistakes...and realized how much more I needed to guard what they watch. I'm just afraid that we are getting used to the dark..and if we don't ask for God's hand over our children...and for His total and complete guidance for our (my) decisions....they are really going to be used to the dark. I was speaking earlier with a like minded friend who was sharing with me the same struggles with her daughter..who is also a very good girl. She gave me such Godly advice that she had used for her eldest daughter. She would tell her daughter...."If you think I'm being overprotective....then pray for me. Pray that the Lord would open my eyes to see that I should give you more freedom". I just thought...wow! What great advice. My children believe in the power of prayer...and hopefully, they realize I'm not just irrational with my decisions. I do almost always try to explain my yes's and my no's. Not that I think they have a right to hear it...but so they will trust me that I have not made my decisions without thinking. It's just such a fine line to walk...and if anybody that reads this has any advice...please, please, please feel free to let me know! I'm open to any suggestions!
