The Duke of Sussex is back in the UK to attend the WellChild Awards, in association with GSK, in London, and HELLO! is there to share all of the heartwarming moments.
Ahead of the ceremony, Prince Harry, 40, was reunited with Noah Nicholson, six, and his mum Tracy, five years after their first meeting at Sheffield Children's Hospital.
The youngster was on lively form, grabbing Harry by the beard and throwing soft toys at him. Admiring a photograph from their first meeting in 2019, Harry spotted that Noah was carrying "Raffy", the same giraffe toy attached to a soft blanket.
"Is this the same one? No way!” he said. "Every parent has a spare. I've got at least six spare."
He added: "My daughter Lili has these Lovies."
As they continued to lark around, he told Tracy, “Good luck!”
Tracy, from Grimsby, Lincs, said: "I'm so proud of Noah. Beyond proud. It means so much. He lives in constant pain, all day, every day. But after everything he's been through, he lights up every room he goes into."
Harry is later due to present Noah with the award for Inspirational Child, 4 to 6 years old and told him: "I'll see you on stage!"
Born prematurely at 27 weeks, weighing just two pounds, Noah has had 28 surgeries, including 14 life-saving procedures.
He has cerebral palsy, chronic lung disease, short bowel disease and other serious health issues that require constant medical care and cause him pain.
Noah is being recognised for "his courage, resilience and unwavering spirit," that has seen him fundraise to support the charities and hospitals that help him and donate gifts for other children in hospital.
The annual WellChild Awards celebrate the inspirational qualities of the UK's seriously ill children, and the professionals who help care for them.
Joining the Duke to honour the incredible recipients is a star-studded line-up of guests, including presenter Gaby Roslin, presenters Kate Garraway and Myleene Klass and Olympic rower Helen Glover.
Last year's awards fell on the eve of the first anniversary of the death of Queen Elizabeth II. Harry paid his own public to his late grandmother in his speech at the charity's ceremony, saying: "She is looking down on all of us tonight, happy we're together, continuing to spotlight such an incredible community."
