Just 18 weeks after his mother died, little Alfie Chivers has died of brain cancer, too.

Two-year-old Melbourne boy Alfie Chivers has died of brain cancer, just 18 weeks after his mum, Sara, died of brain cancer, too.

On Twitter on Tuesday afternoon, ABC journalist Louise Milligan – who first reported the family’s story on 7.30 – broke the news of Alfie’s passing.

“Devastated to report little Alfie Chivers lost his battle with brain cancer last night. Alfie was two. It’s been 18 weeks since his Mum Sara also lost her battle. I’ll never forget them. RIP beautiful little Alfie and gorgeous Sara. Hug your babies people,” she wrote.

In January, little Alfie’s 34-year-old mother Sara died some nine years after first being diagnosed with brain cancer.

“My beautiful sister, Sara Chivers, passed away peacefully in her sleep with family surrounding her on Sunday 28th January,” a message on the GoFundMe page set up to support the family read at the time.

“Thanks to you all for the ongoing support.”

Speaking to The New Daily, Sara’s husband Leigh said his wife looked “like she did on [their] wedding day” after her passing.

“All her features really came out. She looked so young,” he said.

Sara’s mother, Helen Clark, said it was a “privilege” to be with her daughter in her final moments.

“It was actually really, really beautiful,” she said.

“Hard to believe, but it was.”

Just weeks before her death, Sara spoke to Vogue Australia‘s February issue about her devastating diagnosis and her battle to keep her memory alive for her sons.

“It’s surreal to know I won’t see old age. And that I will leave Leigh a single dad,” she wrote.

“I have so much grief for a life I won’t be living.”

In March last year, Sara Chivers was told three aggressive, incurable and inoperable brain tumours had returned years after she first thought she was clear of the disease. In a tragic and incomprehensible turn of events, in that following September, a then 18-month-old Alfie was diagnosed with a rare and terminal form of brain cancer, too.

At the end of last year, the family shared their story with ABC’s 7.30, with $180,000 raised for the family, and even more for brain cancer research.

When the family went public with their brain cancer diagnoses, they family encouraged donations to the Cure Brain Cancer Foundation.
