Importance of Grandparents to Their Grandchildren
Research suggests that children find unique acceptance in their relationships with grandparents, which benefits them emotionally and mentally. Grandparents can be a major support during family disruptions. Sometimes they're playmates for their grandchildren. They're very often role models and mentors for younger generations. They are also historians -- teaching values, instilling ethnic heritage and passing on family traditions.
