A newborn baby died of sepsis after what his devastated mum says was a string of blunders at hospital .
Laura Cooke, 29, says five-week-old Luchii Gavrilescu's death was preventable and no tests were done.
The tot was left waiting for a bed at a hospital for hours with breathing problems and a rash.
"The way Luchii was treated was absolutely shocking," grief-stricken Laura, of Margate, Kent, said.
"You expect to be able to put your baby's health and care in the trust of doctors and hospitals.
"This was completely preventable.
"No Christmas is ever going to be the same for us. It has torn our lives apart."
An ambulance sent to help Luchii after he had trouble breathing at home was allegedly told to turn back on November 29.
When the tot was finally taken in at Queen Elizabeth the Queen Mother (QEQM) Hospital in Margate, Laura alleged he was made to wait for hours. He was eventually diagnosed with bronchiolitis but it's alleged no blood tests or X-rays were performed.
It was advised Laura take her son home but his conditions worsened days later and a GP told the mum to return to A&E.
But when there, she says doctors told her he had a cold and she was sent home with saline drops with no tests carried out. He died in hospital days later on December 6.
She added: "We will go to the end until we get justice for Luchii.
"We can't allow this to happen to another family and for it to tear them apart."
The mum met her 29-year-old partner Vlado Gavrilescu four years ago. He became a first time dad on October 26 when Luchii was born while Laura is also mum to Archie, 10 and Macie, nine.
They were counting down the days to Luchii's first Christmas and had bought him a tiny Santa outfit.
Laura, who is a carer, continued: "I remember the paediatrician saying 'I'm going to start treatment for sepsis please let me do everything now and I will speak after'.
"I started crying and froze and my heart was racing. I sort of went into a panic and didn't know what to do or say.
"My mum came straight over and looked at him and was crying. He just looked lifeless."
She added: "It was just heartbreaking telling my kids their baby brother who they were so excited to have and spent five weeks with was no longer here.
"I had to tell them he had gone to heaven."
"They were asking why and I didn't know how to explain it to them."
East Kent Hospitals University NHS Foundation Trust, which runs the QEQM, has started an investigation into the baby's death.
A spokesman for East Kent Hospitals said: "Our thoughts and deepest sympathies go out to Luchii's family, and we are extremely sorry that they have suffered such a devastating loss.
"We have started a thorough investigation into Luchii's care. We will fully discuss the outcome of this investigation with Luchii's parents.
"Until the investigation has concluded, we are not able to comment on his treatment.
"But we will continue to be in touch with Luchii's family.
"We apologise that they have concerns about Luchii's care and we will work as quickly as we can to be able to give them the answers they need.
"A dedicated key worker is supporting Luchii's family and we have referred Luchii's death to the coroner."
