OK so here's the deal....my very sweet, smart, wonderful daughter is becoming a sassy mouthed, back talking, defient little child. I feel like I'm going out of my mind and I need some advice and support before she gets out of control. I think the biggest problem is that she doesn't understand what she's doind wrong...but than again I talk till I'm blue in the face and that doesn't seem to do any good. I've taken things away, put her in time out, and kept her from doing things that she considers fun. What am I doing wrong and how can I fix this before thing get out of hand???
