Explaining Death to a Child
When talking about death with a child, parents should explain that death means that life stops, the deceased cannot return, and the body is buried. They should also explain their religious beliefs concerning these matters. Anything less simple and explicit often causes confusion and misinterpretation. Covering death over with fiction or half-truths may increase children's fears in the future and lead to mistrust of family members. However, children's fears may be lessened when the death discussion is focused not on morbid details but on the beauty of life.
Possible Reactions of Children to Death
The death of a parent is a traumatic loss in a child's life. Different children cope in different ways. Possible reactions and children's statements that may or may not appear include:
Denial --"I don't believe it."
Bodily distress --"I can't breathe;" "I can't sleep."
Hostile reactions to the deceased --"Didn't he care enough for me to stay alive?"
Guilt --"She got sick because I was naughty. I killed her!"
Hostile reactions to others --"It is the doctor's fault. He didn't treat him right."
Replacement --"Uncle Ben, do you love me, really love me?"
Assumption of mannerisms of deceased --"Do I look like Mommy?"
Idealization --"How dare you say anything against Daddy! He was perfect."
Anxiety --"I feel like Mommy when she died. I have a pain in my chest."
Panic --"Who will take care of me now?" (Grollman, 1967, pp. 18-20).
If parents are concerned about how their children are reacting, they should consult a pediatrician or professional counselor.
