Overview and Birth Order
Princess Charlotte of Cambridge and Prince Louis of Cambridge are siblings who form a stable part of the British royal family’s second generation. Born on 2 May 2015 and 23 April 2018 respectively, they are the second and third children of Prince William and Catherine, Princess of Wales. Charlotte is the eldest of the three Cambridge siblings, preceding Louis by three years, and is fourth in line to the throne at the time of this writing. Louis follows as fifth in line, with their younger brother Prince Edward not yet born. Their ages and order establish Charlotte as a protective older sister and Louis as a lively younger brother, shaping how they are perceived in royal engagements and in public commentary.
Line of Succession and Public Role
Current Position in the Line
As grandchildren of the then-Prince of Wales at the time of their births, both Charlotte and Louis were born with places in the line of succession. Charlotte entered the world when she was fourth behind her grandfather Charles, her father William, and her older brother George. Louis extended that line with his birth in 2018, moving Charlotte to fifth and Louis to sixth at birth before the accession of King Charles III in 2022 shifted both children up one position. As of the present, Charlotte is fourth in line and Louis is fifth, with their positions reflecting the enduring importance of female-line succession after reforms that replaced male-preference primogeniture with equal primogeniture for those born after 28 October 2011.

Charlotte and Louis have appeared together at a range of family engagements, from Trooping the Colour and Royal Ascot visits to Christmas services and public walks on the Mall. In these settings Charlotte, as the older sibling, often takes a steadier, more composed role, while Louis exhibits the curiosity and movement typical of a younger child.

Schooling and Childhood Environment
Charlotte’s Education
Charlotte began her education at Willcocks Nursery School in central London before joining Thomas’s Battersea, a private preparatory school, in 2019. The school is part of the co-educational Thomas’s group, which also operates schools in other London locations. Her curriculum emphasizes core subjects, creative arts, and physical education within a structured yet supportive setting. In September 2022, Charlotte transitioned to Marlborough College Pre-Prep in Wiltshire, continuing a pathway that keeps the Cambridge children in a consistent educational environment close to their home at Kensington Palace.
Louis’s School Experience
Louis joined his sister at Thomas’s Battersea when he reached nursery age, and the pair have attended the same schools during their early years. This shared schooling arrangement supports a stable family routine and allows the siblings to spend regular time together away from the spotlight. As with Charlotte, his early education balances academic basics with opportunities for sport and the arts, reflecting the family’s emphasis on a rounded childhood. By moving together through the same institutions, Charlotte and Louis maintain a familiar daily rhythm despite their public status.
Family Context and Sibling Influence
The Cambridge household emphasizes normalcy for its children, and the relationship between Charlotte and Louis is central to that effort. As an older sister, Charlotte has opportunities to model leadership and responsibility, while Louis benefits from learning alongside her in both classroom and recreational settings. Their interactions at home and in school provide a counterbalance to the formality of royal duties, helping to ground their experiences in everyday sibling dynamics. Within the wider family, Charlotte and Louis share a close bond with George, and together the three siblings represent the future public face of the monarchy in their generation.
Notable Events and Milestones
Key moments in Charlotte and Louis’s early public lives include their first balcony appearance with their grandparents and parents in 2015, their walkabout at Trooping the Colour in 2017 and 2018, and their attendance at the National Service of Remembrance in 2018 and subsequent years. More recent appearances include visits to schools and charities with their parents, where Charlotte and Louis have participated in activities ranging from sports days to arts workshops. These events highlight their gradual introduction to public service while preserving a sense of childhood normalcy, and they offer a consistent narrative of the siblings growing up within the royal framework.
