This is going to be one of those threads where predominantly people with zero experience of the issue, in this case experience of a child with issues and all that encompasses pass simplistic judgement calls.
I know a fantastic parent , dealing with a child with issues . There simply is no reasoning, no calming down, she survives by dealing with him in her way because that's what gets her through the day.
From an outside view, letting bad behaviour pass, seems like bad parenting, but it's just not that simple.what works with normal kids doesn't work on kids who are simply wired differently with conditions.
I'm absurdly lucky to have two well behaved, easy kids, being a great parent is significantly easier under those conditions.
Try years of anger management, doctors, shrinks, medications, tests, etc, then pass judgement.
Note, I have not seen the program, I'm generalising about kids with issues.
