Princess Eugenie took to Instagram today to share a heartwarming snapshot of her sons August and Ernest meeting their newborn younger sister.
The 36-year-old princess revealed this afternoon her baby daughter would be called Adelaide Elizabeth Annina Brooksbank.
"Two weeks ago today we welcomed our girl to the world. And since then we've had the most special, cosy and love-filled time," she wrote.
The name includes tributes to "three people we love and admire".
Adelaide draws on both English and Portuguese heritage.
The name is thought to reference Queen Adelaide, consort of King William IV, as well as Maria Adelaide of Portugal.
Elizabeth, meanwhile, is a tribute to Eugenie's late grandmother, Queen Elizabeth II.
Upon announcing the news on Instagram, Eugenie also shared two touching photos of her sons as they met baby Adelaide, likely for the first time.

The first tender image shows five-year-old August and three-year-old Ernest gathered around their baby sister, who lay in a onesie beside a toy.
"Augie and Ernie are already the best big brothers," their mother declared on the post.
Another shot captured the tiny hands of Adelaide, Ernest and Eugenie clasped together - a particularly poignant portrait of the growing family.
A third image pictured the young Adelaide wrapped in a pale blue blanket.

"Such a beautiful name and lovely pictures," one fan said.
A second noted: "Augie, Ernie and Adie? Lovely sibset."
"What a beautiful name to match a beautiful daughter," a third stated.

Baby Adelaide was born on Monday, August 3, in Lisbon, Portugal, making the newborn just the third member of the British Royal Family to arrive on foreign soil in over a hundred years.
The infant, weighing six pounds nine ounces, was delivered at 6.20pm local time.
Eugenie first revealed the pregnancy in May, posting an Instagram photograph of her sons, August in a grey long-sleeved top and Ernest sporting a Chelsea kit, proudly displaying a baby scan image.
