The surviving child of a horrific house fire in the New South Wales Hunter Valley doesn't know her three siblings have died, as she and her mother remain in hospital.
Twin sisters Matylda and Scarlett, aged five, and their 11-year-old brother Blake died after flames engulfed their home in Singleton at around 3.30am on Wednesday.
Heroic neighbours used garden hoses to save the children's mother, Kara Atkins, 31, and her daughter Bayley, 8, but the twins died in hospital, while Blake died inside the house.
The family said Bayley is still in shock, and is processing what happened last night.
'I've just spoken to her grandmother and she said she is sitting up in hospital watching TV, she doesn't know what's going on, she doesn't know she's lost her family, she doesn't know she has lost her brothers and sisters,' cousin Gary Bates told the Daily Telegraph.

Twin sisters, aged five, and their 11-year-old brother died in the fire at around 3.30 on Wednesday morning.
Ms Atkins is at John Hunter Hospital with burns to her body, while Bayley is being treated for smoke inhalation.
Mr Bates' wife Debbie Garland said the grandmother of the children is distraught.
'I was just speaking to Kara's mum, she said "I've just lost half my grandchildren in one day",' Ms Garland said.
'All we know is Bayley is in hospital, she is oblivious to what has happened, she doesn't know. She is in hospital, she must be in shock.'
Police were seen leaving house with a heater on Wednesday night before taking it away in the back of a trailer, as it's revealed investigators suspect the blaze may have started in the wood combustion heater.
According to NSW Fire and Rescue, the heater will play a role in helping investigators piece together what caused the deadly inferno - which is believed to have started in the front of the house and moved to the back.
A string of fires in the Hunter Valley region were caused by fireplaces and heaters recently, as residents try to keep warm with plummeting temperatures.
Tributes for the three children are being placed outside the burnt out home - among them was a photo of Blake in his local team's rugby league jersey, with letters from the community.
The inferno started at the front of the home on Brittliffe Close in Singleton about 3.30am on Wednesday, and spread quickly through the rest of the home.

A GoFundMe has been launched by family friend Caitlyn Stemmer to help the family, who in addition to losing three children, have lost all of their belongings and their home.
She told Daily Mail Australia she was not surprised to see how quickly donations had flooded in, noting it was 'pretty standard for Singleton' to help out their own.
'I don't have much to say, there's not really words for a situation like this,' she said.
'Money should be the least of their worries, I'm glad the community has come together to support the family.'

Terrified residents woke up in the middle of the night to piercing screams coming from the home, and while some dashed in to help evacuate the property, others ran over with hoses to try and fight the blaze.
Neighbour Shandelle Reid, 27, told the Newcastle Herald she saw flames 'skyrocketing out of the roof' and heard an explosion as part of the Atkins family home collapsed.
Ms Reid also revealed the harrowing experience of another neighbour who had gone in to help the family.
'This lady, she went into help,' she said.
'She said she pulled one of the kids through the back window, but the frame collapsed in and she said she couldn't get in there to get the other kids.
'But she said she kept hearing them screaming.'

When emergency services arrived, the blaze was too strong for them to enter through the front door, but firefighters were able to pull two six-year-old girls out of the blaze.
The girls were taken to hospital, but could not be revived and were pronounced dead.
An 11-year-old boy was found inside the house after the fire was brought under control and could not be revived.
Mrs Atkins has suffered burns to her forehead and back, but she and her daughter, who is being treated for smoke inhalation are in a stable condition at John Hunter Hospital.

A neighbour said she had been awoken to screams next door, and came out to see the home was on fire.
'There were so many children inside,' she told Nine News. 'It is just a shocking thing to happen to anybody.'
Neighbour Brock Forbes told the ABC he and his family had grabbed the hose and rushed to help while they waited for firefighters.
'Me and me family just woke up from a big bang and [we heard] just smashing and screaming so we ran out and grabbed the hose,' he said.
'I was trying to put the fire out and trying to save them and firefighters came and got it under control.
