Doctors discovered Arthur had caught parvovirus, which led to severe anaemia, a build-up of fluid and heart failure.
Doctors discovered Arthur had caught parvovirus, which led to severe anaemia, a build-up of fluid and heart failure.
Specialists at St George's Hospital in London gave the infant what is known as an intrauterine transfusion (IUT) when he was about the size of an avocado and his mother was 16 weeks pregnant.
His mother, Maisie, a 30-year-old primary school teacher from Cranleigh in Surrey, said it was 50/50 whether her son would survive, but the procedure was successful and he was now a "really chirpy little boy".
Medics believe Arthur is the youngest patient in the UK to have had the procedure.
Parvovirus, also known as slapped cheek syndrome, is usually harmless to children but Arthur was extremely unwell because of his immature immune system.
Maisie described the procedure in 2024 as "absolutely terrifying".
"He was so small the doctors were working within millimetres," she said.
Arthur, born in January 2025, was "doing great" and "reaching all the milestones", she said.
"To have the life I am now living, with my family, there's no words to express the gratitude I feel and how fortunate I was to be able to access that care and blood promptly," she added.
She said she often wondered who the donor was, adding: "I would love to tell them that their decision to give blood gave my boy the chance to be here."
About 180 IUT units are issued each year by NHS Blood and Transplant (NHSBT), using blood from donors who must meet strict criteria.
Paul Bickley, 45, from Richmond, one of eight donors whose blood has been used most often, said: "I just realised life is very precious and that kept me donating. Hearing my blood was used in this way almost made me cry."
David Smith, 64, a donor from Westminster, said: "If you can help babies, you have to. It's always a pleasure."
Dr Anne Kelly, paediatric transfusion and components clinical expert for NHSBT, said IUTs were very rare, donors were carefully selected and extra safety measures were applied, because patients were "particularly vulnerable".
Consultant paediatrician and chief medical officer at St George's, Dr Luci Etheridge, added: "A blood transfusion while still in the womb can mean the difference between life and loss.
"We are proud to provide this highly-specialised, lifesaving care."
