My DS is getting out of control - too much fb, Internet etc, disrespectful to me and the family, rude, not making an effort at school etc etc. there is no stand out event or situation that has occurred but i can see him slipping in to arrogant, cocky, rude teenager mode .... so next week I will sit down and have a serious talk with him about acceptable behaviour and considering taking his phone etc away for a bit but any time I have tried this before it has created a bigger distance / void between us. Any tips on how to handle this or can anyone recommend books on this subject. Thanks
