I have a daughter that sounds just like him. Doesn’t take no for an answer seems to ignore oh rules, which she should be following at nine years old. But the main thing is that if you really feel he is or could become sociopathic, then you have to start now hugging your child physically more than others. Sociopathy is a genetic predisposition but not a determination. Parenting makes a great deal of difference, but especially your display of empathy and hugs. Giving hugs sounds like a cure-all that is easy, but it is not when the child is yelling and screaming at you all the time. Often times, parents in practice will feel turned off and want to push the mean child away who is pulling the dog’s hair or spitting at you. For sociopathic predisposed children that may be a mistake. In your case it may be better for you to run into the fire and away from it. That’s why giving a hug is hard in those specific instances, because it goes against your gut reaction. Time out will only reinforce the isolation that leads to emotional detachment that is the hallmark of non-empathic sociopaths.
