Arianna went to daycare and never came home. Six years later, her grieving parents are still fighting for answers

August 24 2018 started like any other day for Jozef Maragol and Anet Eyvazians when their 16-month-old daughter Arianna was dropped off at childcare.

The toddler's carers at Berry Patch Preschool in Kellyville Ridge in Sydney 's north-west placed her in a cot at about 9am.

Arianna was found unresponsive three hours later and died at The Children's Hospital at Westmead, where an autopsy was inconclusive.

Her heartbroken parents are still desperately seeking answers as to why their firstborn died all these years later.

The distraught couple said they had 'trusted' that their daughter would be taken care of.

'No one told us what happened,' Ms Eyvazians told Seven News .

'We had to find out through the doctor that she had passed away. That's how much value the life of child has in the childcare system.'

Adding to the parents' ongoing grief, an inquest date into Arianna's death has still not been set.

'It's unacceptable,' Mr Maragol said.

'Our family has been put through such prolonged suffering.'

Ms Eyvazians called the preschool that morning to check on Arianna and was assured that 'everything is fine'.

It's understood staff at the centre used security cameras to monitor toddlers' sleep movements rather than physical checks.

In 2022, the Berry Patch preschool and its owner, Helen Jacobs, were found guilty of 13 charges, including failing to appropriately supervise children and protect them from harm.

In total, they were fined more than $140,000. Ms Jacobs is appealing the charges, which did not relate to Arianna's death.

Speaking to ABC at the time, Mr Maragol said 'The early childhood regulation needs reform'.

'How can someone pass away and the penalties are monetary penalties?

The couple claimed that the Berry Patch centre had never contacted them after their daughter's death.

Arianna's mum and dad continue to advocate for better regulation in the childcare sector.

'She lived such a short life on this Earth,' Ms Eyvazians said in 2022.

'I hope that she's so proud of us, that we can make changes and be her voice.

'To save other kids and not let any other families, any mums and dads, go through this nightmare.'
