This book, What Makes a Father: The Father-Son Relationship That Impacts Each Other's Lives, written by Michael Diamond, a senior trainer at the Los Angeles Institute of Psychoanalysis, examines the evolving dynamics of the father-son relationship across different life stages. It addresses the confusion and challenges fathers face, from early childhood where fathers act as "guardians" and teach healthy gender awareness and emotional regulation, through adolescence where they must balance setting boundaries with supporting their son's independence. Finally, the text explores the adult phase, emphasizing the need for fathers to adapt to a more equal footing and accept their son's autonomy and imperfections. The overarching message highlights that fatherhood is a journey of self-growth, requiring fathers to relinquish control and embrace the reality of their sons as independent individuals, ultimately fostering a stronger, more authentic bond.
