Does anyone out there know how to deal with an 8 year old daughter who has started answering back, being disrespectful to us in particular, doesn't understand the word no, and who says she is too old to have a time limit or even a time curfew for being on electronics (computer/ipad etc). I have tried being positive, we have tried rewards which work short term, we have been really nice and we have tried not to react to her when she is doing this. We of course have even tried the yelling and screaming and yet nothing works.......it's as though she is on a mission to send us insane. I could understand that if she was 13 or so but not at 8. Please help, I love my baby so much yet I'm lost as to what to do next and it is stressing me out.
