She needs therapy I agree, possible meds, and wouldn't it be nice to put her over your knee and give this child a spanking, back in our day that seemed to work, but can be thrown in jail for it now.
I find her flirting with her Dad not normal the hair thing took the cake for me. Has the school ever tested her for any LD's?
She seems very attention starved and this could spell for alot of trouble going into her teenage years. As the old saying goes the apple doesn't fall far from the tree, there is something not right with this child and my heart goes out to you especially!
