Little Walter Wailes, who is just 10-months-old, has been on a liver transplant waiting list for four months.
The waiting became too much for Walter's parents, and so his father, Evan, has decided to give his son a significant part of his own liver.
Walter's life-saving procedure is booked in for just a few days before the 25th, and the family are hoping for a true Christmas miracle.
According to Kidspot, a liver splitting procedure is extremely complicated, and has only ever been done once before in Australia.
Evan Wailes will also be the first father to donate part of his liver to his child in Australia... what an amazing man.
Adorable little Walter was diagnosed with billiary atresia back in April, when he was just nine-weeks-old.
This is a disease that effects the way in which toxins and waste products leave the body, and can be fatal.
The family have set up a fundraising page, as Evan will have to take three months off work.
The two surgeries will take place next week, and we are all hoping for a great result.
