When my son was three (last year) I had to tell him that he would not see his best friend, my mother anymore. She was sick for quite some time and he knew that. When I knew she was passing I told him Grandma was very very sick and wouldn’t get any better. I then said she was going to go away to heaven. I didn’t use the term “death” or “dying” because I didn’t think he knew what that was but AMEN for PBS – Kids because the next evening Caillou was all about kids dealing with death. We watched it together and he got it.
