I am not a parent so I am suggesting what my parents did with my sister when she was that age. It kinda worked with her (stopped the bitching), but didn't stop the "I'm better than everyone else so buy me 300$ in clothing." She learned when she got a CC and racked up some hefty charges and my parents wouldn't "fall in line" and help her out .
