Prince Harry retraced his mother's footsteps today as he put huge grins on poorly children's faces at the same hospital Diana visited 30 years ago.
The Duke of Sussex was met with cheers as he arrived at Sheffield Children's Hospital and stepped out of his car into the baking sunshine where throngs of people were waiting for him.
Once inside, the playful duke left youngsters in fits of giggles - including one who he had a tug of war competition with.
He was then seen looking lost in thought as he studied a book of photos showing mum Diana's visit.
The Princess, dressed in red, is seen chatting to staff, as well as a mum and her young baby.
Harry smiled to himself as he flicked through the pages.
He then signed the same visitors’ book she wrote in on November 29, 1989.
The hospital visit is the first of three engagements in the city for the Duke today.
The 34-year-old is officially opening a new multi-million pound wing at the hospital and rolled up his shirt sleeves as he took a tour and met children on one of the new wards.
He looked happy and relaxed as he showed off his paternal side while chatting to the youngsters, including schoolboys Heath Keighley, 11, and Alfie.
Harry, who welcomed son Archie with wife Meghan Markle in May, couldn't hide his delight as he spent time with Noah Nicholson and his mother.
He left the 23-month-old in fits of giggles as he put a blanket over the toddler's head.
At one point, playful Noah - who was fascinated by Harry's beard - was seen trying to put his finger in the Duke's mouth, much to his amusement.
Harry then continued to pull a number of silly faces before even having a tug of war contest with Noah and the blanket.
He also clutched the toddler's hand and tickled his stomach.
Outside the hospital, he spent time speaking to more children who he shook hands with and bent down to speak to.
After this stop, Harry visited Sheffield Hallam University to learn about their commitment to applied learning in teaching and research.
He saw a demonstration of a virtual reality rehabilitation project, which uses technology to make it easier for amputees to train themselves to use prosthetic limbs.
He also viewed a racing car built by engineering students and recently raced at Silverstone.
Harry, who is patron of the Invictus Games Foundation, will later visit the English Institute of Sport Sheffield.
He will watch the trials and meet athletes hoping to be selected for the Invictus Games The Hague 2020.
