The Prince and the Duke of Cambridge met survivors of the disaster, community volunteers and charity workers as they visited the new Support4Grenfell community hub which provides help those affected with psychological support.
Harry has previously admitted he struggled in the years after the shock death of his mother Diana, Princess of Wales , only seeking help more than a decade later.
He chatted with pupils at two nearby schools, Kensington Aldridge Academy and Burlington Danes, who said they had been talking and supporting each other following the fire.
Harry replied: “That’s all you can do, is be there for each other because there will be some people... who either don’t want to talk about their experiences... or think they are absolutely fine, and in years’ time, maybe five years time, suddenly they might have some nightmares and that’s when you guys will be crucial, because you have been through that process.”
The hub, based near the charred tower, is a child-friendly area spread over two floors with beanbags, board games and more secluded areas for quiet chats.
The Royal pair were due to be joined by the Duchess of Cambridge, but she was unable to attend due to severe morning sickness, following the announcement of her third child earlier this week.
During the visit, Harry spoke to the Andreia and Marcio Gomes, parents of two that lived on the 21st floor and were expecting their third child.
Mrs Gomes lost the baby boy she was carrying , with police treating Logan as a victim of the fire.
Mr Gomes later said: “I think they understand the tragedy, they’ve been through it themselves as well, which I think is something that’s really close to them.
“And I think they’ve seen so many families impacted by the Grenfell tragedy that they can sympathise and understand what people are going through as families.
“They’re very busy so for them to share their time here with us is an honour.”
Later, the princes travelled the short distance to the Al-Manaar Muslim Cultural Heritage Centre in Westbourne Park, one of the organisations organising the first relief effort for Grenfell survivors.
It helped distribute donations of food, clothing and equipment to survivors in the immediate aftermath of the blaze, but is now focusing on healing the community’s emotional scars.
William also spoke with Syrian refugee Omar Alhajali, 25, who lived on the 14th floor of Grenfell Tower and l ost his 23-year-old brother Mohammad in the blaze.
Mr Alhajali said: “He told me to make sure that I take care of myself and take some time for myself, think about yourself as well.”
“He gave me his condolences.”
The brothers also visited the centre’s prayer hall and met some of the spiritual leaders who have been helping the community.
