“Having a child with Down’s syndrome may have originally been something that was a bit taboo and something that you needed to hide,” she said.
“When we had our launch, I had a dream to have these kids on the billboard in Piccadilly, because I think they deserve to be seen.”
The organisation’s Reflecting Radiance exhibition, which showcased many of the children supported by the group, was shown in Hope 93 Gallery in Westminster and included a takeover of the Piccadilly Lights.
The images were taken by photographer, social activist and Oscar-nominated filmmaker Misan Harriman.
Harriman told BBC London that the children were “amongst the most important human beings that I have had the honour of photographing”.
He added: “My reason to hold a camera is to give a voice to people, who for whatever reason, don’t have one.
“Black children with Down’s syndrome are a minority within a minority. They exist and have always existed.”
The photographer, who is a friend of one of the co-founders, said he had known her daughter, who has Down’s syndrome, since she was born.
“It is such a great joy watching this precious soul figure out the world in her own way,” he said.
