And Duchess Kate also made a promise to the family of a boy who was cared for by her patronage East Anglia Children's Hospice (EACH).

Duchess Kate: "Children's hospices go that extra mile"

Kate spoke to Stuart and Carla Delf, whose 13-year-old son Stuie ran a sponsored 5K every day in the month of May to remember his nine-year-old brother Fraser, who passed in January. Stuie raised over £15,000 (almost $19,000) for the EACH and he told the Duchess he was inspired by Sir Thomas Moore, the 100-year-old war veteran.

She replied: "Oh Captain Tom. Captain Tom has done a lot for this country, hasn't he? He's inspired so many people. You must be very fit, Stuie."

Talking with Carla Delf, the Duchess added: "Children's hospices go that extra mile actually and support families like yourselves, I think it's extraordinary. And, like you say, they consider the whole family as well, which is really important."

After the call, Stuart Delf said: "[The Duchess] said she was going to plant a sunflower in memory of Fraser. I'm not sure which EACH it's going to be, but at one of the hospices." A lovely gesture by Kate - the sunflower has actually been adopted as the official emblem of hospice care...Get the latest updates and more news on the royal family right HERE!
