As a doting mother of three, Kate Middleton has always been respected for her priority on family. And, not only does she take care of Prince George, Prince Louis, and Princess Charlotte, but the Duchess of Cambridge also looks after her sister Pippa, even though they have their own families now. Since they were children, the Middleton sisters have been extremely close to each other, and their intimate relationship has been seen at many public appearances. From royal events to their own wedding ceremonies, Kate and Pippa have shown that there's an adorable sisterly bond between them. Here, we take a trip down memory lane to look at lovely moments between the Middleton sisters over the years.

Catherine and Philippa were each born at Royal Berkshire Hospital in 1982 and 1983 respectively. They came back to the UK in 1986 and were raised there. Their parents’ upbringing style was supportive as they pushed them to participate in activities such as field trips to earn badges, sports, and needlework. The two sisters also stayed together for most parts of their daily activities.

The adorable picture of Kate and Pippa was captured when they were small in Jordan. Standing next to their father, they made funny faces and smiled at the camera.

Pippa and Kate both attended St Andrew's Preparatory School and Marlborough College in Wiltshire. However, while Kate took a gap year and studied in different institutions around the world, her sister achieved an all-rounder scholarship in Marlborough and graduated from the University of Edinburgh with an English degree.

In this picture taken in 2006, Kate Middleton and Pippa were peacefully strolling the yard of Windsor after attending a rugby match that William played in.

The girls were caught talking happily with each other while watching Prince William playing in a polo match in 2006. While Kate was shining in her red dress, Pippa sat next to her in a sky blue skirt.

In a blue glittering outfit, Kate was seen letting her hair down with her sister at the Day-Glo Midnight Roller Disco in 2008. At that time, the pairs were so happy and excited at the party for charity.

Kate and her sister were spotted standing in front of the Goring Hotel in London to celebrate the day before her wedding ceremony. They smiled so brightly in casual clothes with their mother Carole.

The sisters made it memorable by wearing twin shoes when they attended their friend’s wedding. While Kate mixed them with a black and white dress, her sister mixed and matched them with a green coat.

During the Men’s Singles Wimbledon Final in 2012, the close siblings were spotted chatting about something fun. With simple but elegant clothes, they both giggled and got closer to talking to each other comfortably.

Catherine tied the knot with Prince William in 2011 at Westminster Abbey in London, England. She has known him since college and has a family of five after 11 years. Their marriage is always admired by people all around the world. Moreover, on the special day of her sister, Pippa showed up amazingly as Maid of Honour and cheered for her.

Pippa Middleton walked down the aisle with James Matthews in 2017 with wishes from everyone. Their destiny started in 2012, although there were some breaks after that. The couple has happily stayed together since then and is the parents of three children. On Pippa’s day, the Duchess appeared in a pink dress and took care of her sister with the bridesmaids and page boys.

In 2019, people saw Kate and her sister attending a tennis game at Wimbledon. Watching their favorite sport, the two showed great reactions with matching black glasses and sometimes giggled a bit.

The Duchess’s sister is a mother of three, one of which is a three-year-old son Arthur, born in October 2018. Her first daughter, one is one-year-old Grace, was born in March 2021 and the second arrived in 2022. Pippa’s children are free from public attention so they can enjoy a more relaxed childhood with the support of their aunt, Kate.

Just like her sister, Kate also has 3 children, 2 boys and a girl. They are Prince George, Princess Charlotte, and Prince Louis, who are under great care from their parents as well as the royal people. Kate always wants their children to have as normal of an upbringing as possible. George and Charlotte once attended Pippa’s wedding as page boy and little bridesmaid.

When Kate celebrated her Christmas concert at 2021 Westminster Abbey, her sister and parents appeared to support her. They arrived in delicate black outfits that went well with the theme.

During the first years of William and Kate's romance, Pippa regularly accompanied her sister to royal or sports events to watch the Prince compete. Here, the sisters were chatting to William as he played the Field Game at Eton College in 2006.

The famous sisters got several pictures captured when they showed up at a 2007 Book Launch Party. Kate and Pippa surprised people with the same hair and matching A-line dresses.

Being famous as the Duchess’s sister, Pippa does not rely on that but becomes her boss as an author and a socialite. She is recently focusing on her studies and managing areas of wellness. The ambassador for the British Heart Foundation in 2014 gets so much support and love from her sister as well as people around the world.

Kate is attached to a busy work calendar as a senior member of the British royal family after working as an accessories buyer in the past. She is devoted to the royal responsibilities and her family is set to move out of London during school term time, in a bid to give their children a normal family life. Her sister, Pippa, always stays there with her when she fulfills her duties.
