4 year old won't listen...

I also have a four year old and I think its a stage they just go through because she has had nothing but attitude lately, but all you can do is when you say no make sure you stick to no. I have also took toys away and tried timeouts but never worked she didn't care. I have learned that she wants to be treated like a big girl, so I started a sticker chart and gave her a list of things to do daily for ex..listen to mommy and daddy, clean room, and etc...and I explained to her everytime she did those things she could put a sticker there and when she got so many I would let her pick one thing to have or do(inexpensive).hope this was useful, just try to make listening into a game...should help...
