My 11 year old daughter is failing at the moment in many levels eg self care, bedroom tidiness, getting up in the morning, planing her homework etc etc. I believe that her access to her mobile phone isn’t helping as she’s too engrossed. So I attempted to bring in a screen time limit on the iPhone. I think she has somehow managed to hack it so that TikTok YouTube etc are always available. So instead I attempted this weekend to bring in a physical restriction instead so that she hands me the phone and I return it to her each day when I’m happy she has everything in order. Seemed reasonable to me. She refused. And when I took it off her she just took mine and switched it off and hid it. And has since refused to give it back laying all kinds of sass on me. How can I handle this please? It’s causing so many arguments.
