A mother dropped to the floor and screamed in anguish when she saw doctors trying in vain to revive her baby daughter.
Charlotte Cooper had spent two years trying to get pregnant with her husband Andrew before Heidi was born on September 27 last year.
Nine months later the 39-year-old mum took her little girl to Wishaw General Hospital with a viral sickness bug, only to be sent home after two days of care.
The mum, from Airdrie, Scotland knew something was wrong when Heidi woke from a nap shortly after leaving hospital and wouldn’t stop crying, had a fever and couldn’t keep food down.
While a visit to a local health centre seemed to sooth the baby a little, Charlotte took her back to hospital a day later with her fever still raging.
Heidi was taken to a treatment room where six doctors worked on her, giving her fluids and antibiotics.
One of the medics told the worried mum that her little girl was septic and that she needed to be transferred back to Wishaw General Hospital for surgery.
It was there that tragedy struck.
“Just before we reached surgery, Heidi’s heart stopped – I will never forget that moment I saw doctors giving her CPR,” Charlotte said.
Charlotte fell to the floor and screamed “no” as she watched on, her husband dragging her away from the tragic scene.
The doctors managed to start Heidi’s heart, allowing her to be intubated and put on life support.
A mobile intensive care unit whisked the battling baby to Queen Elizabeth Hospital in Glasgow.
Her arrival came too late however, with doctors pronounced her brain dead a short while later.
With the family gathered around Heidi, the decision was made to switch off her life support.
“Looking at Heidi and touching her cold head, listening to the sounds of the machines, I knew she was gone,” Charlotte said.
“I held her in my arms as she was pronounced dead, it was the worst moment of our lives.”
Charlotte said: “I never believed Heidi was dangerously ill, nor did I understand that she was in a life or death situation.
“Now, we just have to keep busy and find little things to do each day, but it still feels like a hell we can’t escape from.
“Andrew would like to try again for another child, but I don’t think I can – nothing can replace Heidi and I know I would be anxious at every little cough and sneeze.”
Although Charlotte has been through a traumatic time, she isn’t put off giving advice to other parents, as she explained: “Parents needs to know more about sepsis as it kills so many people.
“I can’t help but think that if we knew more about sepsis she could still be here now – I would have insisted it to the doctors and asked her to be checked sooner.”
