Little Reuben was diagnosed with acute myeloid leukaemia (AML) at just 10 months old.

His mother Mary, a paramedic, said he had been unwell “for a few days” with a persistent fever, but she and husband Ashley initially thought he was teething.

The couple took Reuben - nicknamed Roo - to the GP, who suspected tonsillitis.

However, follow-up tests resulted in the family being advised to go to hospital, where blood tests showed Reuben had AML.

Mary said: “We never thought it would be anything like leukaemia, it blindsided us. He’s just a baby.

“We knew of leukaemia, but it didn’t seem possible for it to be happening to us, we thought it was so rare.
