No two children respond exactly the same way to the death of a love one. Children are likely to respond to death differently and need different kinds of help, depending on their prior experience, their age, and what happens after the death. Young Children Children, ages 2 to 7, mainly miss the loved one who has died. They feel sad that they are not with the person anymore, as if the went on a long vacation. This does not mean your child believes in ghosts, simply that he or she does not understand that death is really the end.
Understanding comes with continued patient explanation in simple terms.
Remember Sara, Grandma died. That means that we won't see her again. Explain your family's spiritual beliefs about death in very simple terms. But be prepared for the likelihood, that your young child may repeat what you say and then behave like he does not understand what death means. Make sure your child doesn't feel at fault.
