This generation of kids is legalistic & argumentative. When they err you have to take time to correct. Don’t assume their obedience – you have to cultivate it. Don’t loose them to cartoon sectarianism. Do not punish – but correct. They will remember reprimand as war against them -because parent you allow their mind to be belligerent exposing them to cartoons & digital game. Anti-parent combat is in the air all the time. They think you are the monster – peers are their only friends. Don’t confront – face off the conflict. Approach again softly. Engage them on a topic they like. Then come to the sore point. You need time. On your feet don’t scold them in between preoccupation with smart phone or TV. Only effective medicine is you giving time.
