Harley Jones, two, from Mochdre, did not hesitate when his brother, Briely, one, cried out in pain after he clung to a boiling hot radiator at the family home. Harley immediately tried to douse his siblings wounds with a cold drink that he was carrying and then ran to get a first aid kit.

The children's mother, Carly Seddon, 27, was left 'shocked' and 'terrified' when the one-year-old started to scream. She phoned her neighbour, Connie Messenger, who dashed to help and they decided to call the ambulance. Ms Seddon said: "He was trying to climb onto the window sill, over the sofa and he accidentally slid down the radiator, skin was coming off his stomach. It was horrible, I was terrified."

Mother of four, Ms Seddon, undressed Briley to see the extent of his injuries and Harley, who calls his brother 'Bibi,' wrapped him in his Thomas the Tank Engine blanket.

Neighbour, Mrs Messenger was amazed by the youngsters actions. She said: "My mouth just dropped. I just couldn't speak. He tried to give his brother a toy and then ran to get the first aid kit. No-one even had to mention it he just did it. It was brilliant."

Briley, who has two other brothers, Seth, 7, and Ryan, 6, was treated at Glan Clwyd Hospital and given morphine to ease the pain. His wounds were then bandaged up. The youngster will return to the hospital to assess the extent of the burns.

Ms Seddon said: "He never parts with his Thomas blanket and he gave it to his brother. It was a terrible day, but Harley put a smile on my face when he helped Briley."Dr Rob Atenstaedt of the National Public Health Service for Wales, an NHS run organisation said: "Home injuries are very common in children. Many ordinary things in your home - bath water, electrical outlets, even some food - can burn your child."

Dr Atenstaedt advised parents that a number of things can be done to try and avoid such incidents for example establishing a 'no zone' area in the home and mark it with yellow tape and reducing water temperature by setting your thermostat lower.
