Olivia was badly injured when she stepped on the dark-grey basalt tiles on a balcony heated by the sun at the family's home on November 10.
It was later discovered the tiles had heated to 69degC.
Her mother, Angela McRae, took Olivia to Dunedin Hospital yesterday to see a plastic surgeon, who was taking a "conservative" approach to the possibility of skin grafts, with the hope of avoiding them.
Olivia would see the plastic surgeon again next week, but a decision would not be made until the following week. The consultant was taking photos of her feet to check progress.
Painkillers were helping, but there were difficult and painful times, particularly changing her dressings, and when she woke at night, Mrs McRae said.
She was very mobile, having started to walk at 11 months, and had adjusted to her injury by walking on her knees. To protect her knees, the family had fitted knee pads.
While she was not blaming anyone for the accident, Mrs McRae said people should consider the possible heating hazard before laying dark tiles.
She and her husband, Andrew, had now laid outdoor carpet over the tiles, which were in a particularly sunny, sheltered spot.
The tiles were open to the sun, but also received filtered sunlight through glass balustrades, which probably exacerbated the heat factor.
Mrs McRae, who until recently was treasurer of her local Plunket branch, had been surprised by the accident as she thought the couple's home, which they built themselves, had been "baby-proofed".
She said subsequent medical care had been excellent, and she was pleased treatment had been provided in Dunedin rather than Invercargill, as Dunedin was where both sets of grandparents lived.
Olivia's older brother and older sister were coping well with the disruption.
A spokeswoman for the Queenstown Lakes District Council said she hoped the "sad accident" raised awareness of the potential dangers of sun-heated tiles.
The Building Code did not regulate tiles other than for their potential slip factor, she said.
Building Industry Federation chief executive Bruce Kohn said tiles' heating factor came down solely to colour.
He was amazed the Arrowtown tiles reached 69degC, but said it was not uncommon for dark-coloured roofs to reach those temperatures.
Light-coloured tiles' glare factor might put some people off them, he said.
