A heartbroken mother who found her 'extremely healthy baby' lying dead in her cot one morning has revealed her two surviving children, age eight and six, still say goodnight to their little sister.

Liz Willcox put five-month-old Jasmyn down to sleep 7pm at her home in Kilcoy, north-west of Brisbane, on a winter's night in 2017.

She was woken 12 hours later by her eldest child Natasha, who was five at the time, and realised the infant hadn't woken up like she normally did at 4am for a feed.

The now 32-year-old opened up to Daily Mail Australia on Monday about the moment she looked at the baby monitor and realised 'something wasn't quite right', before racing into the infant's room and grasping at her cold and lifeless body.

'My husband Ben came ran into the room and started doing CPR, and then the ambulance came and took her to hospital, but it was too late,' she said. 

'Jasmyn had already passed.'

When the couple were told Jasmyn had died from sudden infant death syndrome, they felt as though they had failed as parents.

SIDS is when a baby under the age of one dies suddenly, usually in its sleep. The cause is unknown.

'Your one job is to protect your children, and even though there is nothing we could do, we felt like we failed because we couldn't protect her,' the devastated mum said.

An investigation revealed that nothing was out of the ordinary and that Jasmyn was otherwise in excellent health.

She was not in a high-risk category, meaning there was no cigarette smoke in the house and she was asleep on her back when she died rather than on her stomach, which can cause suffocation.
