Six-year-olds learn from many sources: friends, school, your friends and mostly, you. She will be your pride and joy once she learns that *you* are confident about helping her learn the right way to treat others by your example.

There's a tiny trick to make sure that your action is completely respectful -- kids have very sensitive BS detectors. Still, she lives in your house and you only lose control if you want to. Keep your cool and focus on a measured response to her misbehavior.

Tell her, "I'm sorry, but what I said is how it's going to be and [your sass] doesn't work. You're getting a 20-minute time-out to think about it (or another real punishment that's appropriate to your lives and immediate situation). Do you understand that if you can't be polite with others, your voice doesn't count?"

Another part of this is to make sure she gets POSITIVE reinforcement for good choices. Make sure she gets lots of chances to make appropriate, realistic choices -- whether it's A or B as her bedtime story, beans or greens for veggie tonite, whatever fits. All kids need to try out what they see others do, so it isn't enough to just stifle the bad activity.

All you have to tell her is to listen to you or else i will put you out. If that does not work just tell me

I recommend you to read a book from A.S. Neill called Summerhill - A radical approach to child rearing. I personally don't agree with everything he wrote, but it makes you think and be a better parent. I hope you will read it...
I'm Jana from Serbia by the way...

I blame the parents. Take some parenting classes or read a book about it.

i would either hit her on her mouth or bottom or you need to talk to her. i have a son that is 1 and he is very whiny so i just leave him or hit him on the mouth. its your choice.

Obviously the person who says they blame the parents has no children of their own. I agree that our children do learn from us and we need to be very careful how we treat others, but children have a sin nature all of their own and will test the limits like every person walking the face of this earth. Rearing children is the most difficult job in the world. I find myself being challenged by my son everyday. One thing we all must do is pray for our children on a daily basis.

I agree that the personwho says they blame the parents must not have children of their own. My almost 6 year old daughter is going through a phase of back-talking me.  Anyone who knows me knows that I am very strict and if I say I'm going to do something then I do it.  There are definitely repercussions for her actions.  So, it certainly, in my case, NOT an issue of her not knowing who is boss.  This I am having problems with.  I've tried logic ("if you can't say anything nice, don't say anything at all" and "mommy wouldn't tell you something that was wrong, so if I tell you something don't argue with me, just say okay mommy"), taking things away, quiet time, spanking, etc.  Nothing is working.  I'm just going to keep trying various punishments until I find one that works :)  Hopefully this phase is short-lived.
