"We were really shocked. Obviously, we weren't confident parents because she's our firstborn. She's only young," Michael confessed.
"I guess you need time being a parent to wise about these things and understand what they are."
Their 3-year-old daughter had a severe asthma attack, according to her diagnosis when she arrived at the hospital.
Kelsey Lee was immediately prescribed Ventolin and was told to take six puffs each day.
Michael and Kyly were also introduced to a digital device known as Respiri, which measures wheezing and helps asthma sufferers detect early signs of an attack.

The parents said Respiri - which stores daily results in an electronic diary that can be sent to a doctor - has provided them with a peace of mind.
"Now if I feel if something is not right, I've got an option to get some information into my brain before making a decision," Michael said.
The knowledge the technology provides the couple has given them the ability to know what action to take should their daughter suffer another attack.
"Do we need to give her the puffer? Is she going to be fine and she doesn't need anything, no medication? Do we need to take her to the GP, or do we rush her to emergency? Now we have some options."
Respiri costs $300 and is yet to be approved by the Therapeutic Goods Administration.
