Princess Eugenie has shared new photographs of her baby daughter Adelaide, marking four weeks since the birth of her third child with husband Jack Brooksbank.

Adelaide Brooksbank was born on August 3 in Lisbon, Portugal, weighing 6lb 9oz (2.98kg). She is the couple's first daughter, joining brothers August, aged five, and Ernest, aged three.

The princess posted three images on Instagram: one showing Eugenie holding the baby against a sunny background, another of Adelaide cuddling with her brothers in matching outfits, and a third of the boys kissing their sister's cheeks while she lay in a blanket. The first photo was captioned "4 weeks of ", while the image of the siblings together carried the caption "Happy days with my babies".

Her name, Adelaide Elizabeth Annina Brooksbank, was revealed by Eugenie in a social media post two weeks after the birth. In that post, Eugenie wrote: "2 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 described Adelaide as "Named after three people we love and admire past and present, including her Great-Grandmother who we hold close in our hearts." Eugenie also noted that the name "is part of English and Portuguese history, two places we love and call home," and added that "Augie and Ernie are already the best big brothers."

Adelaide is the late Queen Elizabeth II's 15th great-grandchild and is 15th in line to the British throne, behind August and Ernest. She holds no title and will not be styled Her Royal Highness.

The baby's name is believed by some to honor either Queen Adelaide, wife of King William IV, or Maria Adelaide of Portugal.

Eugenie confirmed she was expecting her third child in May with a social media post showing August and Ernest holding a baby scan, captioned "Baby Brooksbank due ".

The couple, who married in 2018, own property south of the Portuguese capital where Adelaide was born. They are believed to split their time between Portugal, where Jack works, and Ivy Cottage on the grounds of Kensington Palace when in the UK. The last royal born abroad before Adelaide was Princess Lilibet, born in California in June 2021.
