Hello all! new to mumsnet... I take my daughter's laptop off her on school nights at 10pm, but just discovered she is using her mobile to go on facebook and tumblr til late at night which makes her so tired and grumpy in the morning. Is it going too far to take her mobile off her too at 10pm do you think? Or just take out her sim so she can still listen to music, but no internet maybe? Would appreciate your views, my ex says I would be making her a prisoner if I take her mobile off her.
