After some encouragement, Maud rejoined her parents and grandparents – Prince and Princess Michael of Kent – for the remainder of the photos.
Lady Gabriella married Thomas Kingston at a noon ceremony on Saturday at the Windsor Castle chapel.
Maud, her younger sister Isabella Windsor, Leonora Weisman, Aurelia del Drago, Eliza Goldsmith and Emily Conolly were all bridesmaids, with Frederick Murray, Rafferty Murray and Karim Khawaja as pageboys.
Earlier, the group of youngsters had walked into the chapel for the ceremony hand in hand, wearing outfits created by wedding gown designer Luisa Beccaria.
No stranger to posing on the steps, Maud was also a bridesmaid for the wedding of Princess Eugenie and Jack Brooksbank.
At the October wedding, pageboy Prince George and bridesmaid Savannah Phillips got up to their playful ways, pictured giggling as they waited for Eugenie to arrive.
