w.o.w. – First of all, think about what your saying. Your child is sick because of a severe trauma that HE experienced. Does that sound like something that could be contagious? (ridiculous). Healthy children will make healthy decisions. Like I said before, No normal healthy child would “choose” to do what he is doing. Furthermore, eventually you may need to explain to the other children what this mehalach is all about; but first you have to understand it yourself. BTW, my kids do it better than my wife and I do.
Secondly, what aries2756 said about boundaries is great for healthy children. YOUR CHILD IS BROKEN, if you would enter 2+2 in his “calculator” it would equal 7. No normal parenting will work at this point. You’ve been trying that for a long time already, has it worked so far? You said it yourself, he’s only getting worse. You are wasting precious time grasping for straws that are getting you nowhere. Remember, I’m here to help, but you gotta be ready and totally committed, You and your husband.
