Say what you want about Prince Charles, there's no denying that seeing the future King of England in the role of proud father and grandfather has shown a whole new side to the soon to-be 70-year-old.
Despite raising his sons in extreme circumstances, not only with the glare of the world's spotlight on Prince William and Prince Harry but also having to deal with the immeasurable loss of their mother, Princess Diana in 1997, Prince Charles has always put the well-being of his two boys first.
And clearly, his hard work has paid off.

Prince William, 36, and Prince Harry, 34, are arguably the most popular royal members in recent history and the pair are not only charismatic, but also stand-up role models, paving the way for issues close to their heart including mental health, veteran support, and gender equality.
William has become the ultimate family man, a dedicated husband and an adoring father preparing to become the Future King of England all the while giving his two children, Prince George, five, Princess Charlotte, three, and Prince Louis, six months, the most normal upbringing possible.
While Prince Harry has totally reinvented himself from problematic party boy, to passionate humanitarian. Inheriting his mother's Midas touch and his father's sense of humour, Harry's is the People's Prince.
The brothers were only 15 and 12 when they lost their mother and they credit their father for being an incredible pillar of strength in the heartbreaking aftermath of her death.
"One of the hardest things for a parent to have to do is tell your children that your other parent has died. How you deal with that, I don't know," Prince Harry explained in the 2017 BBC documentary special Diana, 7 Days.
Adding: "But he was there for us. He was the one out of two left. And he tried to do his best and to make sure that we were protected and looked after. But he was going through the same grieving process as well."
Indeed, Charles' dedication to his sons while balancing his duty has clearly impressed his boys.
In May this year, during a garden party at Buckingham Palace held to mark his upcoming 70th, Prince Harry praised his father's legacy and work ethic.
"Pa, I was again struck by the range and diversity of the work which you are involved with," a proud Harry beamed.
"Currently there are your two major charities, The Prince's Trust and the newly formed – Prince's Foundation – which has brought together your work supporting vulnerable young people in society, the built environment, culture, heritage and education. These sit alongside your 18 military associations and more than 420 patronages, ranging from music and the arts to rare breeds and plant life."
"Although the subjects vary enormously, I know that the way in which you work with each of them does not."
"His enthusiasm and energy are truly infectious; it has certainly inspired William and I to get involved in issues we care passionately about and to do whatever we can to make a difference. In fact, many of the issues William and I now work on are subjects we were introduced to by our father growing up. You have inspired William and I," he added.
In recent years, we've seen Prince Charles in the heartwarming new role as grandfather to William and Kate's three children.
Even Charles admits he melts around them!
"[They'll] look after me when I'm tottering about," the royal has affectionately mused of his grandkids.
As Prince Charles prepares to ring in his milestone 70th birthday on November 14th, we look at the Prince of Wales' role as a father and his best moments with Prince William and Prince Harry.
