Writer Hannah Mills had not long been back to work part time in a job she loved, when her youngest child, Kit, was diagnosed with acute lymphoblastic leukaemia.
"My husband, Ben, and I had just been congratulating ourselves that we were finally out of the parenting trenches," Hannah told Mamamia of the weeks just before Kit's diagnosis in August 2022.
"My daughter, Edie, was at school and Kit was enjoying his time at daycare. We had been through the toilet training, and toddler sleep issues were mostly behind us."

After a long winter filled with regular viruses, Kit developed a cough and some nasty fevers he couldn't shake, and following a weekend of illness, Ben took Kit to the emergency department.
"It was a Sunday and they had to wait eight hours to be seen while I stayed home with Edie. The doctor on duty ran some blood tests that proved his white cell count was low and explained why his little body couldn't fight the succession of winter bugs. Initially we felt optimistic, but when doctors admitted Kit for a bone marrow biopsy to look further into his condition, we were worried.
