How do you handle your eight year old back chatting daughter?

If it's innocent back talk, think first about how you speak to her. It could be that she's getting her cues from you and just giving it back. Bickering is addictive, and you'll never get the last word.

Then sit down with her and promise to speak with kindness and respect to one another. When you talk to her, look her in the eyes and tell her clearly what you expect, say please ONCE and let it go. If she talks back, don't answer her and don't repeat yourself. If she engages you, don't fall for it. She'll get the hint that she can't push your buttons like that.

If on the other hand she gets aggressive and disrespectful you will have to come up with a proper punishment and make sure to follow through.

wait till she's 15....lol....i'm dealing with that to some extent just now it's a huff at me and eye rolling.

Anyhow, Best thing to do is ignore it, when she does it.

Or

You could sit her down and tell her look you like living here right? Well to live here you have to do certian things to earn your room and board and food. And those things are chores. If you dont want to have those things then dont do the chores.

She'll change her mind really quick the first time she goes with out dinner.

Did it with my step kids and i'll tell you for the most part they dont give me to much guff over nothing.

Get a handle on this now and it shouldn't become a problem

You can always use the ticket method. In the morning, she gets three tickets. Each time she backtalks you, she has to give you a ticket. When she gives the last one out, she is in her room for the rest of the day and has to go to bed one hour early. It's helpful if there is nothing amusing in her room, no tv or computer. Actually, there shouldn't be a tv or computer in a child's room anyway, too much potential for harm.

If she's doing this at 8, then you have taught her that it's ok. I wouldn't put up with it for ONE SECOND, but that's a choice you have to make. Imagine what's going on in her mind to think she can do this without consequences, and the potential of what this attitude will result in once life gets more serious in a few years.
