Dd1 is 13 in Nov.
I am having problems with her mouthing off at me when she is having a strop. She does it all the more if there is an audience and I am sick of it.
Last timme she did it at dd2's swimming lesson, so I told her she earntt herself an 8pm bedtime. She carried on and I told her that if she continued, she could go to bed at 8pm for for the next 4 nights. She still carried on and so she did indeed go to bed at 8pm for the next 4 days.
Anyhow, she has just done it again in front of neighbours and so as she was due to go to a friends house tomorrow afternoon, I have told her she can't go. I did warn her beforehand.
She carried on again, telling me how she was going and I can't stop her etc. I again warned her that if she carried on she'd get sent upstairs, but she did and so is now upstairs.
I have no problem carrying through the punishment, but nothing seems to work with her, I just get a mouthful back.
