Their understanding of the world and their ability to comprehend death changes as they grow and move through developmental stages. Clear and accurate communication appropriate to their level of comprehension, as well as unconditional listening and affection are critical in helping children through a potentially traumatic time.
Children are largely unable to articulate their fears, feelings and needs.
It is our responsibility as adults to provide them with ways to express themselves, allowing them to work through grief issues. If your family suffers a loss, communicate with your children's teachers. They need to be informed so they can help your youngster cope with the situation. Some of the behaviors can be explained by the simple fact that grieving takes energy. The child may require more sleep than before.
