Here is a list of things you can do to help a child overcome loss. Children are concrete in their thinking. Answer their questions about death simply and honestly. Only offer details that they can absorb. Don't overload them with information.
Children can be fearful about death and the future.
Don't offer false comfort. Give them a chance to talk about their fears and validate their feelings. Offer a simple expression of sorrow and take time to listen. Children are repetitive in their grief. Respond patiently to their uncertainty and concerns.
