It seems that the royals are keen to loosen up the rules this year, whether that's Meghan Markle going against tradition [1], or Prince William and Prince Harry generally breaking all the rules [2].

The Duchess of Cambridge isn't exempt from going against standard royal protocol either. On Tuesday the duchess, who is expecting her third child in April [3], visited the Royal College of Obstetricians and Gynaecologists to be officially named its royal patron [4]. There was a heartfelt moment during Kate's visit where she stopped to hug a woman inside the college, and the reason behind their exchange is equally as sweet. While walking with Professor Lesley Regan, the president of the college, Kate recognised a very familiar face. As it turns out, this woman helped Kate through one of the momentous moments of her life. Jacqueline Dunkley-Bent, Professor of Midwifery, helped deliver Princess Charlotte [5] in 2015, as she was working on the Lindo Wing at St Mary's Hospital, London, at the time. Ahead, see more photos of their heartwarming reunion.
