The royal family, through Catherine’s constant support and mediation, has helped William navigate his roles as a devoted father, a dutiful son and a future king. Her efforts to understand and respect the views of both the older and younger generations have helped create a more cohesive and supportive family unit, bridging the generation gap that is essential to the continuity and relevance of the monarchy in the modern age.

The relationship between Prince William and his father, King Charles, has had its challenges, with historical tensions and recent arrangements testing their relationship. A significant point of contention was Williams’ use of a private helicopter to ferry his family around, despite being an experienced pilot. Williams’ decision to ferry his wife and children between their homes caused concern from both the Queen and King Charles. Royal editor Robert Jobson’s book Catherine reveals that Williams’ refusal to heed his father’s advice on protecting the succession led to a formal request from King Charles for William to sign a document acknowledging the risks involved in this disagreement.

Highlighting the ongoing issue between Williams’ desire for autonomy and the Royal Family’s emphasis on tradition and safety. Catherine's role in mediating the conflict between William and King Charles was crucial, described as emotionally mature and someone who always tried to see both sides of any dispute. Catherine helped bridge the gap between Father and Son. Her ability to empathise with both sides and provide a balanced perspective played a key role in easing tensions and fostering a closer relationship between William and Charles.

A senior Palace source noted that in recent years, William and Charles have grown much closer, with William respecting his father's dedication to service despite the adverse impact it had on their relationship while raising him. Catherine's stabilising influence not only helped William see his father's point of view, but was also appreciated by King Charles, who appreciated her positive impact on his eldest son. One of the most important ways Catherine influenced William was by encouraging him to adopt a parenting style.

More hands-on than his father, Williams wanted his three children, Prince George, Princess Charlotte and Prince Louis, to look back on their childhoods with a sense of love and affection, a testament to Catherine's influence. William often spent quality time with his eldest son George, demonstrating their close bond with George's world. The man who insisted on dressing like his father when he was with him began to imitate Williams' style whenever George seemed shy or overwhelmed. William was always close by to put a protective hand on his shoulder. This gentle and affectionate parenting style contrasted sharply with King Charles' more distant approach during Williams' childhood.
