Princess Charlotte showed her empathetic, caring side with a subtle gesture to her great-grandmother, the Queen, during their appearance on the Buckingham Palace balcony in the closing moments of the Platinum Jubilee celebrations.
The young royal joined the Monarch, Prince Charles, Camilla, her parents the Duke and Duchess of Cambridge and her brothers George and Louis for the historic moment following the People's Parade.
But body language expert Judi James revealed Charlotte's quick act proved just how like her mum Kate she is.
She tells The Mirror: "Charlotte stood to attention and sang the anthem as confidently as Louis beside her but she again showed her empathetic, caring side.
"When Beatrice was sobbing uncontrollably during Prince Philip ’s memorial it was Charlotte who threw her a concerned glance, prompting Beatrice to smile to show she was ok.
"Here it was Charlotte throwing a similar look of caring concern to her great grandmother as the family sang the National Anthem.
"She seems to have inherited the trait from Kate, who stroked Louis constantly to keep him happy and who bent down to his height to talk to him once he had taken his place in the line-up."
The Queen was forced to miss Friday and Saturday's engagements, which included Epsom Derby and a Service of Thanksgiving, after the first day of events left her in pain. She's suffered a series of mobility issues in recent months.
Judi also believes we learnt a lot about the Cambridge family through their engagements over the long weekend.
As well as traditional engagements, we've also seen them in a much more relaxed setting including singing and dancing along at the BBC's Party at the Palace concert.
She said: "William towered over the group but his smile of pride has been growing steadily throughout this weekend.
"His and Kate’s hard work with their children has clearly paid off.
"Not only have they been happy and playful with the Tindalls but they have also, in a very natural and spontaneous way, produced several PDAs to signal unity and strong bonding across the generations."
We've seen a number of adorable moments from Princess Charlotte over the Jubilee, including her attempts to calm down her excited little brother during their carriage ride at Trooping the Colour. She slaps down his overly enthusiastic wave before holding his hand.
She was also seen sharing a cute, intimate moment with mum Kate as they watched the Party at the Palace on Saturday night.
