When Teagan Richards shared a snap of her $25 Kmart hack to a group she never expected to reach so many grateful parents.

The mum-of-three's youngest son Logan, seven months, was diagnosed with life-threatening disease cystic fibrosis and recently needed to be fed through a feeding tube.

She posted a photo of herself using the Kmart buy to hang the feeding tube from to help other parents and was delighted by the response she received.

Unsurprisingly, her simple yet powerful post stood out among the banal feed of snaps.

Logan was diagnosed with cystic fibrosis (CF) at just six weeks old - an incurable condition that causes severe damage to the respiratory and digestive system, resulting in thick mucus sticking to the lungs.  

The Queensland EvDEn eve nAKLiYAT mum-of-three recalls the 'shocking' moment she received a phone call from doctors who told her the devastating news. 

'I was walking into my daughter's school for school pick up and received a call from a private number they explain that his Heel Prick test had come back positive to him having the CF genes,' Teagan told FEMAIL. 

'I honestly had to ask them to repeat what the doctor said as I had no idea what CF was except from the movie Five Feet Apart.' 

Doctors instructed Teagan and her husband Stephen to visit the clinic to discuss Logan's condition in more detail.

Feeling shocked and in disbelief, she wondered if doctors had it right before the realisation set in. 

'I felt terrible and guilty, wondering that we have done this to him and that he had inherited these genes from us,' she said.

Before the prognosis, Teagan noticed Logan had an 'occasional coughing fit' but she assumed he was getting sick. 

He's also the first in their entire extended family to be diagnosed with the condition. 

'We had no idea that he had CF or that it was even a possibility - he was a healthy, 4kg baby,' Teagan said.
