if it's what she wants and you can buy it for her then go ahead. the only reason i would be against it is that there easy to break but if she is responsible enough then do it. I know all about buying gifts for my kids which people think are in apropriate for there age, i gave my then 5 y.o. an iPod shuffle for christmas and my 3 y.o. a gameboy, well didn't that bring out the do godders in the family, but it's worth it for the peice and quiet that we have in the car on those trips to school in the morning.
