An Australian 3-year-old was described as a hero after saving his mum from an almost certain death by calling emergency services right after she collapsed(because of an epileptic attack (癫痫发作).
Aiden McDonald amazed the doctors who arrived at Jeanine McDonald’s house 10 minutes after Aiden called 000. The boy was very calm and spoke to the doctors as his mother got into an unconscious state.
Sasha Lewis took the strange call and sent out an ambulance immediately. Aiden answered questions during the 19-minute call that made it clear it was a serious matter.
Lewis said: “He sounded worried and was telling me things like ‘Mummy is not awake’, so I got an idea that it was a fairly serious matter.”
This is part of the “conversation” they had:
“Can I talk to Mummy please?”
“Mummy’s not well.”
“How old are you, sweetheart?”
“I got a clock.”
“Can I talk to Mummy?”
“I can’t get my Mummy.”
“Where is she?”
“On the floor. Mummy’s had a fit （昏厥）.”
“Do you live in Kallangur?”
“We’ve got milk in the fridge and, um, (pause) I can’t find the ambulance (crying), Mummy, Mum ... Mum ... Mum ...”
Mrs McDonald, who was making a cup of tea when she collapsed, was taken to hospital and allowed to leave the same night. “After hearing what he did I thought, no, that can’t be right,” Jeanine McDonald said. “But I’m so proud.”
