When 37-year-old mum Helen Stock from Reading found herself slipping into a diabetic coma, her four-year-old son, Luke, sprung into action and saved his mum's life.

Upon feeling her blood sugar levels dropping, Helen struggled to say conscious, but thankfully quick-thinking Luke who had been taught about his mum's condition since the age of three came to the rescue and phone emergency services.

Recalling the traumatic event, Luke's mum said: "I started to shake and fit and was foaming at the mouth. It's hard to remember, it was traumatic and I blacked out. The next thing I remember I was coming in and out of consciousness."

The terrified mum woke up to find paramedics at her side administering treatment and Helen can not thank her young son enough for having the peace of mind to seek help, saying "I'm just so proud of him. He saved my life."

Helen hopes her experience will encourage other parents to teach their children how to contact someone in the case of an emergency because, in some circumstances, it could be a matter of life and death.

Commenting on the importance of this, Helen said: "I want to get across to all parents it's never to early to teach children the basics. Luke knows how to call 999, what his address is and to tell them his mummy is diabetic and has gone wobbly."

It's certainly a week for quick-thinking little boys with one three-year-old tot in the States having been hailed a 'hero' by police officials in recent days!
