"I had the fire going and was playing with Brett in the lounge," Mrs Oosthuizen said. "It wasn't the first time the fire had been going but we honestly believed we had such a clever little chap. If he looked at the fire or got close to it we said no and he lost interest."
But on this day the toddler's interest was more than piqued, and while his mother left the room for mere seconds, there was no one to say no.
"I heard this funny little cry and rushed back into the living room. Brett had his hands held out in front of him and all I could see were white patches."
After rushing her son to running water, Mrs Oosthuizen was about to apply Burn Aid when she thought it might be best to first call a doctor. "I phoned the Tarawera Medical Centre and was told not to put anything on the burns."
Once at the centre, the doctor knew immediately Brett's burns were deep skin burns and he was referred to Whakatane Hospital. There, photos were taken of the injuries and sent to a plastic surgeon at Waikato Hospital.
"We were taken to Waikato that night and stayed for two weeks."
Mrs Oosthuizen said it was Brett's reaction to the injury that kept her calm during that first day.
"He knew something was up with his hands but he didn't scream or cry at all."
Since then Brett has had a number of surgeries including doctor's cutting away most of the skin on both hands because the burns were so deep. Skin grafts are continuing.
"When we were thanking our plastic surgeon for his incredible work and support, he asked that we let people know about what happened to Brett so they can make sure it doesn't happen in their own homes."
The Oosthuizen fire now has a guard to prevent further mishaps. And Brett is managing nicely with his bandaged hands.
