'We can't believe Olivia got Laura out, she's six-years-old and ran in a burning building.'
An investigation into the fire is currently ongoing but the family have been told it might have been caused by a phone charger.
But Ms Gelder said nobody actually went into the house to rescue Laura and the children, because they didn't think anyone was home.
She said: 'Olivia saw people in the street but she just ran in to wake her mum up.
'She was shouting 'wake up mum, the house is on fire - wake up the babies.'
'The people in the street didn't think anyone was in because there wasn't a car on the drive.'
Sadie says that the family are now staying in an Airbnb because they have lost almost everything in the blaze.
A fundraising page has been set up by Laura's former colleagues to help support the family.
Sadie said: 'They managed to get a few of the baby's clothes but everything else has gone, including their birthday presents.
