Nearly as soon as they appeared on the Buckingham Palace balcony to watch the planes of the Royal Air Force in their traditional flypast, Kate Middleton's mini-me and her older brother were bringing the cuteness alongside the Queen's granddaughter, Savannah Phillips, with claps and giggles all around.

Since her first appearance in 1981, Princess Diana also maintained royal tradition by wearing dresses with sleeves that went past her elbows during the Queen's public birthday celebration.
Britain's Prince Harry, Duke of Sussex and Britain's Meghan, Duchess of Sussex travel in a horse-drawn carriage down The Mall to Horseguards parade ahead of the Queen's Birthday Parade, "Trooping the Colour", in London on June 9, 2018.
Meghan looked chic in a dress by Carolina Herrera and a hat by Philip Treacy, while Kate was stylish in an Alexander McQueen dress and a hat by Juliette Botterill. Thankfully, Super Mom Kate Middleton was there to help steady her 3-year-old daughter.
She was without her husband, the Duke of Edinburgh, who turns 97 on Sunday.
Her procession was accompanied by a Sovereign's Escort of the Household Cavalry, made up of Life Guards and Blues and Royals, in their silver and gold breastplates and plumed helmets.
They watched as this year's colour, the flag of the 1st Battalion Coldstream Guards, was trooped on Horse Guards, Henry VIII's former jousting yard. Back in 2012, the Queen took Kate, Duchess of Cornwall, for such an "away trip", this time to Leicester at the start of her Diamond Jubilee tour marking 60 years on the throne.
Black, grey and white horses, military guards including the Cold Stream and Irish guards in their elaborate dress uniforms and tall fur hats, and two enormous drum horses bearing kettle drums and riders took part in the ceremony, which ran for two hours.
Today's ceremony was also the first royal outing for Meghan Markle, Duchess of Sussex, since she returned from her honeymoon.
"Both of us have passions for wanting to make change, change for good, and, you know, with lots of young people running around the commonwealth, that's where we'll spend most of our time hopefully", Harry said shortly after the couple's engagement was announced in November.
