Winners from the Awards included Henry Waines, four, who was born with serious health problems and appeared on the call with his parents Ben and Shevonne. His parents had actually named him after the dad-of-two.
Laughing at the little boy's enthusiastic chatter, Harry told him: "You sound just like my son Archie really. The same little squeaky voice. I love it."
Henry's parents asked him: "How are Archie and Lilibet doing?" The Duke told them: "They're doing great…Archie is very, very busy. And Lily is learning to use her voice, which is great."
Prince Harry looked delighted to speak with the winners
The Duke and his wife Meghan Markle had been due to attend this year’s WellChild ceremony on 8 September, but pulled out so Harry could travel to Scotland as concerns grew for his grandmother the Queen.
In the video, shared exclusively with Hellomagazine.com, Harry spoke from his home in America to each winner and their families and apologised for not having been able to meet them in person.
The Duke of Sussex shares his two children with his wife Meghan Markle. The couple are raising their family in Santa Barbara, California. Their lavish Montecito mansion features everything from a spa and tennis court to an outdoor pool and private playground.
