I've heard that the teen years can be difficult, but my once timid 12 year old daughter has become quite frankly demonic at times. She has moments where she is completely out of control, and swings between being completely irrational and screaming at us one minute and then hugging you the next and wanting to spend time with you. Is this hormones? Poor thing has had her period for at least a year and is quite developed for her age. Any one experienced the same?
