Princess Charlotte's tears for 'Gan Gan' at the Queen's funeral
* Queen Elizabeth II laid to rest following moving funeral and procession
* Heartbreaking moment the Queen's loyal corgis wait for her at Windsor
* Princess Kate's touching funeral tribute to Her Majesty Queen Elizabeth
Princess Charlotte was comforted by her mother as she cried as she farewelled her great-grandmother at the Queen's funeral at Westminster Abbey.
The 7-year-old royal wiped her eyes in a touching moment as Her Majesty's coffin was lowered into the hearse at Wellington Arch.
Kate, the Princess of Wales was by her side to provide support as the young princess bid her final farewell.
Both Charlotte and her older brother Prince George, 9, showed composure beyond their years during the emotional service.
Kate was also seen to reassure George inside the abbey when the young prince rubbed his eye as the Waleses joined other members of the royal family and the world in a final day of mourning.
Their little brother Prince Louis, 4, was deemed too young to attend.
Charlotte, who is third in line to the throne, paid touching tribute to her "Gan Gan", as she called her, with a small detail in her outfit.
Charlotte wore a horseshoe brooch on her black dress, in what was a sweet nod to the Queen's well-known love of horses.
Her Majesty gifted the young princess with the brooch, which is made of diamonds.
Later, Princess Charlotte was spotted reminding her older brother Prince George of royal protocol during the Queen's final send-off.
Charlotte, 7, was seen telling George "you need to bow", as their great-grandmother's coffin passed by en route to Windsor following the state funeral at Westminster Abbey, reports the Daily Mail.
The Prince and Princess of Wales' two older children joined the senior royals at the funeral service and procession.
The Queen's great-grandchildren sat solemnly and quietly during the funeral.
After the service, the Queen's coffin left Westminster Abbey to begin its final journey to Windsor, where she was later interred during a burial private to the royal family at the King George VI Memorial Chapel in St George's Chapel.
As the casket passed them by, Charlotte could be seen reminding George, "you need to bow". He appeared to follow his sister's instructions, bowing his head as the coffin passed.
Meanwhile, Prince Louis is struggling to understand the passing of his great-grandmother, Queen Elizabeth.
The four-year-old royal is said to be confused by the monarch's death and has been asking his parents lots of questions about what life will be like without the 96-year-old sovereign.
The 27th governor-general of Australia David Hurley attended an event with other world leaders at Buckingham Palace hosted by senior royals over the weekend, and he shared how Catherine, Duchess of Cornwall and Cambridge told him her little boy is "sort of now realising how important his great-grandmother was and what is going on."
He added: "The younger one is now asking questions like, 'Do you think we can still play these games when we go to Balmoral' and things like that, because she's not going to be there?"
