The first-time parents were unsure what to do, so they took her to hospital.
"I think you rang the ambulance and in the mean time I said ''nah, I'm not going to wait for the ambulance, get in the car'," Michael said.
"We were really shocked. Obviously we weren't confident parents because she's our firstborn. She's only young," said Kyly.
"I guess you need time being a parent to wise up about these things and understand what they are.
"We just looked at each other and thought best case scenario is to rush her to the hospital … she just couldn't breathe properly."
While at the hospital, they were told Kelsey-Lee had had an asthma attack.
They now manage the condition using a Ventolin inhaler, and a 'Respiri' – which helps monitor those with asthma and detects early warning signs of an attack.
"The great days - there's nothing better in life, but the other part is quite scary," Michael said of life being a dad.
According to the Global Asthma Report 2018, approximately 339 million people on the planet have asthma. Worldwide, about 250,000 deaths annually are attributed to asthma. One in 10 Aussies are affected.
