"I have tried hitting her, taking out of school and keeping her locked in her room, but nothing has worked". If you do this it will only make worse & she'll feel like she has a point to prove.the more you let them be, the sooner she'll stop.I know this because I went throuhg this with my mom & aunts,it's like when you say NO! to her you mean OKAY DO IT. With the peer peasure she's getting things couldn't be any worse.When they started allowing me to be I got bored,because I didn't have to prove to anyome that "I'll have it my way or no way at all".So grams let her be she'll get bored sooner than you think.
