What you are describing is grief, not empathy or remorse.
Has anyone modeled it for him? Explained it to him?
Adults can be very careful to protect children from sadness, so much so that we don't show them our own. We tell them big boys don't cry, etc., and then expect them to show their emotions appropriately.
Also, does he understand death?
If you're concerned, talk to a counselor, and have him evaluated, but it may be something as simple as him not understanding death.
How do I talk to him about this?? I tried to. But it obviously it didnt work. Yes! He's on a wait list to see psychiatrist through his family doctor. What are your suggestions to help him through this
May I suggest you take him to a psychologist? He may have just "walled" himself off to stop the pain he might have to face with the loss of loved ones in such a short span of time.
