I dont think that kids should get everything that they want, because when they do its never enough and its not appreciated. It sounds like she may be depressed though and usually people like that need new things to "make them feel good about themselves" I would probably suggest a psychologist just in case, I didnt get everything that I wanted and I turned out just fine, whereas my parents made that mistake with my older sister and she throws it in their face now that she always got everything that she wanted and why should it change now. I'm not saying that I wasn't spoiled but my parents did tell me no every now and then....Maybe you could come to a compromise. Good Luck
