Wellchild.org states that the WellChild Awards celebrate "the inspirational qualities of the UK’s seriously ill children and young people, along with those who go that extra mile to make a difference to their lives."
On Tuesday, Prince Harry - who became a Patron of WellChild in 2007 - met with the young winners of each award category and their families.
According to Express, Dexter (one of the Award winners) was diagnosed with Leukaemia in 2018 and he became known at the hospital for arriving dressed as a superhero and his positive spirit.
The royal couple also received gifts for their son Archie, including a baby grow and an emoji balloon.
Earlier, Prince Harry appeared to choke up while giving a speech at the awards.
The Duke of Sussex was talking about becoming a father with Meghan when he appeared to hold back tears, with host Gaby Roslin giving him a comforting pat on the back.
"They never fail to inspire me - but this year it resonates in a different way because now I'm a father. Last year when my wife and I attended we knew that we were expecting our first child, no one else knew, but we did," Harry said, recalling how he knew Meghan was pregnant with his son Archie at last year's WellChild Awards.
"I remember squeezing Meghan's hand so tight during the awards and both of us thinking what it would be like to be parents one day and more so would it would be like to protect and help our child should they be born with immediate challenges or become unwell over time," he continued.
