Warwick baby Daisy Stevens will have surgery at the Queensland Children's Hospital (QCH) on her skull next month to make more room for her brain to grow.
Surgeons will remove a large section of bone at the back of the seven-month-old's head and, using specialised tools at a workbench inside the operating theatre, will turn the bone into a "few, different-sized pieces" to expand the skull's volume.
