Grandparents are secondary but essential actors in the family, and their authority is exercised best by supporting and reinforcing the parents’ authority with firmness, consistency, and affection. But should they intervene with their grandchildren? Only when necessary, following the specific guidelines of the parents, without undermining or replacing their educational role, and using love and experience to guide. The presence of grandparents strengthens security and builds emotional bonds that complement family life and the personal history of each child.
