The ceremony was attended by King Charles, Queen Camila, Catherine's parents Carol and Michael Middleton and siblings Pippa and James. Their presence created an intimate and memorable atmosphere for the party. The presence of Catherine's parents and siblings demonstrated the close relationship between the Middleton family and the Princess of Wales. Carol and Michael Middleton have been very supportive of their daughter since Catherine married Prince William in 2011. They have been involved in royal life, attending major events such as King Charles' coronation in May 2023 and Catherine's Royal Carols in December 2023.

The presence of King Charles and Queen Camila added a special touch to the ceremony. The king's affection for Catherine, whom he called his "beloved daughter", is clearly strong. Over the past 13 years, King Charles has supported Catherine on her royal journey. The evening was filled with thoughtful gestures and cherished traditions. Catherine's children presented her with handmade gifts, which brought her great joy. Carol Middleton also played a big part by helping to bake the birthday cake, a family tradition that Catherine loves to continue.

The menu for the intimate celebration was a mix of casual and sophisticated. The meal included roast lamb, fresh winter vegetables and a selection of fine wines. Dessert included a homemade birthday cake, raspberry tart and a selection of Catherine’s favourite chocolates. Catherine opted for a light blue midi dress, accessorised with pearl earrings and her wedding ring. The rest of the family also wore semi-formal attire, creating a harmonious balance of comfort and elegance.

The birthday party also marked a beautiful end to the family’s recent festive season. Catherine and William had previously spent Christmas at Ammer Hall with King Charles and Queen Camila at Sandringham. Carol and Michael Middleton, who live nearby at Adel Cottage, have been by their daughter’s side at important family moments. Their long-standing support continues to strengthen the bond between the Middletons and the British royal family.

Princess Catherine’s 43rd birthday is a testament to the importance of family and togetherness. The warmth and happiness of the evening confirmed that, despite her royal responsibilities, Catherine’s most precious possession was the love and support of her family. As the Princess blew out the candles on her birthday cake, it was clear that this was not just a celebration, but also an occasion to honor the cherished relationships and traditions in her life.
