Queensland grandmother Sharon Wallace said she needs locks on her bedroom door.
That's because her seven-year-old grandson Xavier can be incredibly loving one minute, but destructive the next.
"Xavier loves to have something that smells like me, plays with my ears. And then the other side of Xavier is that he'll put huge holes in the walls at home, he'll hurt his brothers and sisters or me," Ms Wallace said.
"He gets in such high anxiety states of aggression and he won't calm down for ages. He could be fine right now and ten minutes later he's having a big rage and there's no calming him down."
Ms Wallace has to hide knives and hammers from Xavier, because of the damage he can cause at home.
It has gotten worse since he wasn't allowed back to school.
"He says it's payback, but usually it's when he's having his meltdown," Ms Wallace said.
"I think he regrets it afterwards but at the time it's his way of getting his anger out.
"It can be very confronting."
Ms Wallace said the episodes happen up to three times a day.
She has been looking after Xavier and his siblings since they were taken away from their mother because of problems with alcohol.
That was one of the reasons why last year she decided to take Xavier to see doctors at the Fetal Alcohol Spectrum Disorders Clinic on the Gold Coast.
She was looking for answers to his wild and uncontrollable behaviour.
"Nothing else we tried has worked," Ms Wallace said.
