The role of grandparents is very important in our lives both as parents and as grandchildren. The care provided by them is an emotionally influential experience that also serves as an attachment pattern. The grandparents, especially the grandmothers, have had a role in the survival of grandchildren since ancient times. Presumably it was the postmenpausal women, the grandmothers, whom made it possible that human children began to have a long developmental period, which is of great importance in human cognitive evolution.
However, there are a number of questions about grandparental help, answered by researchers with both evolutionary and social explanations. These studies take into account how the grandmother's role appeared during human evolution, what factors influence grandparental help and how the parents and grandchildren will relate to it.
