Princess Charlotte made her first official public appearance during celebrations marking her great-grandmother the Queen's 90th birthday on Saturday.
Charlotte was held by her mother, the Duchess of Cambridge, alongside Prince William, Duke of Cambridge, who held Prince George.
Prior to Saturday, Charlotte had only been seen in public leaving the hospital after her birth and entering the church for her christening.
The Cambridges were among several members of the royal family who appeared on the balcony of Buckingham Palace on Saturday.
The Queen turned 90 in April. Saturday's events were held alongside her second, official birthday.
After various military planes flew over the palace, the Red Arrows gave a colourful display.
Charlotte did not appear to enjoy the experience as much as her brother, George.
Prior to the balcony appearance, a lavish parade, followed by Trooping the Colour, took place at the nearby Horse Guards Parade.
The woman herself wore a striking green outfit by designer Stewart Parvin.
She was joined in her carriage by her husband, Prince Phillip, who turned 95 on Friday.
Prince Charles, Prince William, and Princess Anne joined the parade on horseback.
Princess Anne was riding a horse named Elizabeth, named for her mother, the Queen. Elizabeth (horse not person) will be retired from duty following today's events.
The Duchess of Cambridge was joined by his brother Prince Harry and their stepmother, the Duchess of Cornwall.
Kate wore a suit designed by Sarah Burton for Alexander McQueen, who also designed her wedding dress and many other outfits for the Duchess's public appearances.
Prince Edward and his wife Sophie, Countess of Wessex, were joined by their children in another carriage.
Princesses Beatrice and Eugenie, grandaughters to the Queen, rode with their father, Prince Andrew.
During the event, one soldier fainted, but quickly received medical attention.
Before festivities continued in full force.
Buckingham Palace's household cavalry provided music.
Thousands of well-wishers flanked The Mall, the road leading to royal residence, to witness the celebrations.
