Whether it be a publicity photo or a candid shot, you'll notice a familiar trend in all of the pictures of the royal family.
In nearly every picture, Prince George is tightly holding onto Prince William's hand.
For instance, you'll see George clutching onto William's hand in this year's annual Christmas photograph, and when he's brought to his first day of kindergarten.
While plenty of people chalk it up to a normal father-son gesture, it may mean more than just simple affection.
According to parenting expert, Jasmine Peters, it's not a coincidence the pair are often pictured in this gesture.
Peters said William may potentially be holding George's hand to prepare him for his destined role as the King of England.
