AT 3.30am last Friday, worried mother Kylie Cook checked on her two-year-old son Renato, who was fighting what seemed to be a common cold.
Six hours later the Bathurst toddler was dead - the youngest victim of the killer flu strain that has swept the nation, leaving every parent fearing the worst.
Renato had slept fitfully on Thursday night, much as he had for the previous two weeks.
Mum Kylie checked his temperature at 3.30am on Friday and patted him back to sleep, hoping his cold and flu symptoms would soon clear.
After telling him she loved him, the toddler looked at her and replied: "I love you more."
By 9.30am, he was gone.
In a grim warning to all families, Renato's grieving parents yesterday told of the frightening speed at which the toddler lost his life.
"I thought it was just a cold or flu," a distraught Ms Cook said at her home in the state's Central West.
"He had a bit of a temperature and the sniffles when he went to bed so I gave him a lukewarm bath and some Panadol. He seemed okay. And then we woke to find him like that."
Tests confirmed Renato tested positive for the deadly influenza A virus that has already claimed the lives of five other children and an adult across Australia.
Ms Cook and her partner Renato Martin said their son had been sick for about two weeks and had been given a prescription of Ventolin as doctors tried to work out the exact cause of his illness.
The young couple had taken the toddler to see a family doctor early last week and there appeared to be no real change in his condition.
Renato Jr was suffering a sniffling nose and chest cough when Ms Cook put him to bed as normal about 7.30pm last Thursday.
She woke about 3.30am on Friday and went to comfort the crying toddler.
Having moved him out of his cot and into a "big boy's bed" a fortnight earlier, Ms Cook said she decided to lie with her son after he woke upset.
"We laid there for a while and he seemed okay. I told him I loved him and he looked back at me and said 'I love you more,' " she said.
"It didn't seem any worse than any other night. You just never know."
Ms Cook and Mr Martin said they woke about 9.30am to find Renato slumped in his bed and not breathing.
The couple frantically tried to revive the little boy and called an ambulance, but paramedics were unable to revive him.
"They tried to bring him back . . . they took him to the hospital and then they came out and told us they were sorry there's nothing they can do," Ms Cook said as she clutched her son's treasured Thomas the Tank Engine backpack.
The bag will be buried with the toddler on Friday.
Ms Cook should have been celebrating her 21st birthday today - but instead she will prepare for her little boy's funeral.
She said she never realised there was a more virulent strain of influenza abroad in Australia and regretted not seeking a second opinion after taking Renato to the doctor last week.
"If you are concerned about your child at all just get them checked," she said.
"If you are not happy keep going back until someone listens to you."
Ms Cook said, although there was no way of diagnosing how sick Renato was, she would carry the heartache of his loss for the rest of her life: "There is always that feeling we could have done more - that's never going to go away."
Renato is the sixth child victim of the flu this season, with five others - including three in Western Australia and one in Queensland - to die from the illness.
Two adult deaths from Influenza A have also been recorded including Queensland father-of-three Glen Kindness. Sydney father Joseph David died on July 12.
