Little Jaden Ashton is his mum Brina's lifesaver after she fell into a diabetic coma.

While many might have panicked, five-year-old Jaden stayed calm when he found his mum unconscious and shaking in her bed.

He even measured her blood sugar level before dialling 999.

Jaden, who is in Year One at St Mary's Catholic Primary School in Bicester, has now been nominated for a Chief Constable's Commendation for his actions by Thames Valley Police.

The youngster tried to revive his mother himself by giving her sugarcubes, which she keeps by her bedside, before telling police call handler Vicki James his full address for an ambulance to reach them.

South Central Ambulance Service sent paramedics to Whitley Crescent, Bicester, where they gave Mrs Ashton, 40, an emergency injection of glucagon and put her on an IV drip to bring her out of the coma.

Jaden was the only one at home to raise the alarm at 8.50am on June 26 as his father, Gavin, was at work.

Mrs Ashton, diagnosed with type one juvenile diabetes when she was 18, said she fell into the coma on that day after missing her alarm and having a lie-in.

Although she hadn't fallen into a diabetic coma for more than 10 years, she had trained Jaden to use her blood glucose monitor and had told him anything under four millimoles of glucose per litre of blood (4 mmol/1) meant mummy was sick.

She also told him to call 999 if he could not wake her.

When Jaden took his mum's blood sugar level, the monitor read just 1.9 mmol/l.

Mrs Ashton, a health officer for the National Blood Service, said: "Jaden is my hero. He did so well I'm so very, very proud of him. His actions definitely helped save my life. Jaden told me afterwards I was sweating and shaking and my eyes were rolling so he knew his mummy wasn't very well.

"When I was told what happened, I just cried and gave him a big cuddle for what he'd done. He's a very, very clever boy. He just kept his wits about him."

Jaden said: "I wasn't scared. I just called for an ambulance to make my mummy better."

Chief Insp Jack Malhi said: "I have no doubt that Jaden's quick-thinking and his calmness helped to save his mum's life. For a five-year-old to have that presence of mind and not to panic is really superb."

Ambulance spokesman Neville Wade said: "A diabetic coma can be fatal so the fact that Mrs Ashton got treatment thanks to her son's actions is amazing."
