In May this year Sativa, having already cheated death several times, received a bone marrow transplant, with the hope it would cure her.
But at the end of August, just days before the twins' second birthday she relapsed.
More bone marrow was injected into her body in a desperate bid to push out her cancerous cells, but on September 11 parents Sheree Roose and Tim Eagle were given the devastating news that their daughter was dying.
Sativa's brave, and at times miraculous, journey was charted on the Please Help Baby Sativa & Her Family Fight Leukemia Facebook page, which has amassed more than 5700 "likes".
Originally set up by a friend to support the family, Ms Roose has, over the past year, courageously shared her hopes and darkest fears on the page.
Sativa's funeral, which will be held at 11am on Saturday, at Greerton Bible Church, will have a purple theme - Sativa's favourite colour.
While it will be an open service, Ms Roose asks that people be respectful towards the family, and not approach them unless they know them personally.
