The brave thing a 3-year-old boy did to save his sister's life.

For most three-year-olds, the phrase ‘bone marrow transplant’ isn’t one they’d hear often at kinder.

But for little Lachy Abbott, it became a reality when his bone marrow was matched to his five-year-old sister Amelia’s.

Amelia was battling lymphoblastic leukemia, and was desperate for a transplant.

“It was just awesome – we were just ecstatic to know Lachy was able to help her to heal and be a part of her journey,” Michelle Abbott, mother of the children, told The Daily Mail.

Initially diagnosed in the acute category of the disease, Amelia’s condition escalated dramatically after chemotherapy.

Within just three months, the Gold Coast family were told Amelia was now categorised as extremely high risk and had only a 40-per-cent chance of recovery.

After being told that there was only a 25-per-cent chance of a match between the siblings, the news that Lachy was a complete bone marrow match with this sister came as both a surprise and a relief for the family.

“It was amazing when the news came,” Mrs Abbott told The Daily Mail.

She chose to explain the situation through a superhero story, and Amelia indeed has dubbed her brother her ‘superhero.’

On the 9th of July 2014, Lachy underwent the surgery to have roughly 280mL of bone marrow removed, which was hours later transplanted into his sister.

The surgery went well for Lachy, his body replacing the marrow within a matter of weeks.

‘He woke and all he wanted to do was see Amelia, but she was in isolation so he waved at her through the window,’ Mrs Abbott told the Daily Mail.

Unfortunately, the close siblings were unable to see each other for five weeks, after which they met with hugs and smiles.

After being kept in isolation for 100 days, Amelia will find out her results in a few days, hopeful of returning home to the Gold Coast.
