Foster to adopt teen girls??

We had fostered one teen girl and were planning on adopting her. Needless to say we were NOT prepared for her and her issues!!!! I had no clue what RAD was and no clue how to handle it. Her needs were too much for us so in the end the placement did not work out. I take my hat off to those who can handle teens. Not only do they have the every day teen problems, but they have other issues from being in the system and coming from abuse/neglect etc. I would be cautious if you have other kids in the home. Good luck to you!
