THREE numbers was all it took for eight-year-old Leah Wilson to save her mum's life.
The quick-thinking Hervey Bay Year 4 student has been praised for her calm and clear call to 000 when her mum Chauntal Treyvaud suffered a hypoglycemic attack.
"I'd be in a coma if she hadn't acted so quickly," Ms Treyvaud said.
"She's certainly my little hero. I had a hypoglycemic attack so my blood sugar went down really low so I started to fit.
"Leah noticed and she went and got the neighbour who came over and asked Leah to call the ambulance.
"I dropped my telephone and that was pretty much the last thing I remember.
"I'm extremely proud of her and the fact she was able to keep calm in a scary situation like that."
Chris Henderson from the Maroochydore-based Queensland Ambulance Service Communications Centre was on the other end of the phone when Leah called 000.
"Straight off the bat Leah was able to give her name, full address including unit number and phone number to us, which made the process all that much easier," Mr Henderson said.
"We have children calling through from time to time, but she was just amazing she never panicked and was so well spoken.
"If blood sugar levels are low for diabetics, they could slip into a coma, so the matter is serious and time critical.
"Congratulations to Leah, she helped her mum a lot that day, even just by knowing her address and phone number."
But little Leah was quick to brush off the hero tag and said it was all part of keeping an eye out for her mum.
"A long time ago mum told me if anyone is in trouble at the house and no one was there to help me I just call 000 and she showed me how to use the phone," she said.
