Investigations into the tragic death of a three-day-old baby will continue – after it was revealed an ambulance took more than 30 minutes to arrive following a panicked 999 call.

Wyllow-Raine Lawson Swinburn from Didcot died on September 30 last year, just hours after leaving the hospital.

An inquest into her death was due to conclude at Oxford Coroner's Court today, but it was adjourned to allow for more evidence to be gathered.

Emergency services were called at around 4.38am to the family home in Didcot when Wyllow’s mother, Amelia Pill realised she was unresponsive.

The inquest heard that it took around four minutes for the call to be answered by South Central Ambulance Service and the first responders did not arrive on scene until 5.09am.

Paramedics took Wyllow to the John Radcliffe Hospital in Oxford, but she was pronounced dead within five minutes of being there.

The baby’s grandmother, Anna-Marie Fisher, 51, told the Times back in October: “I'm angry and I want answers.

“I am not going to go away. I don't blame the paramedics.

"This is a system failure. The blame lies with the government.”

Ambulance response times have increased in recent months with thousands of people hit by long waits and overcrowded A&E departments.

The ambulance service aims to respond to category one (life-threatening) calls within seven minutes and to have paramedics on scene within 15 minutes in 90 per cent of cases.

Karen Skillicorn-Aston from South Central Ambulance Service said at the inquest: “I am really sorry for the passing of Wyllow-Raine.

“Unfortunately, we are not always able to provide the level of support that we wish.

“We are sorry that we were not able to answer your call as promptly as we would have like.”

Dr Darren Fowler, a paediatric pathologist gave evidence at the inquest today (June 21).

He said that Wyllow’s cause of death following a postmortem was given as sudden unexpected death in infancy, but why this happened remains unexplained.

Sudden unexpected death in infancy is used to refer to the deaths of babies when there is no apparent cause of death.

Dr Fowler added that normally there are contributory factors that lead to such deaths such as smoking or stomach sleeping but none of these applied in this case.

He said: “In this case I wasn’t aware of any factors like that and I did not find anything anatomically wrong with the baby.

“All the investigations we carried out were negative.”

Oxfordshire’s head coroner, Darren Salter adjourned the inquest today, suggesting it was unlikely that the court would reconvene for another five to six months.
