bzylzy - he is four and he does talk about his concerns while awake. Death is just a part of his concern. He doesn't want to grow up. This is how he explains it: "I was a baby and now I am a little boy. The "baby me" is gone. Forever. I don't want the "little boy" me to go away like that. When I am an "older boy" I won't be the same. I won't think about things the same, or look the same or like the same things. It is like the "me" that I am right now dies more everyday I get older."
I talked to the psychologist about it. He said to tell him he can stay young at heart and that he doesn't have to change. I tried. He seemed skeptical.
He doesn't go around talking about this stuff all the time. He is chipper almost all the time.
