New blow for Aliyah Yugovich's parents after WA health minister refused to answer question about toddler's death

A minister has been forced to issue a grovelling apology to the parents mourning the loss of their three-year-old daughter after she was accused of giving a 'childish and inappropriate' response when grilled about the mysterious death in parliament.

Perth toddler Aliyah Yugovich died unexpectedly in July after she contracted the flu following a tonsillectomy

A preliminary report by the coroner recently revealed that the toddler had been mistakenly been administered an anti-seizure drug by one of the three hospitals which treated her.

Opposition leader Libby Mettam asked WA health minister Amber Jade Sanderson in parliament on Tuesday if a lack of resources at Perth Children's Hospital was a factor in Aliyah's death.

In reply, minister accused Ms Mettam of politicising the tragic case, saying the Liberal leader had 'plumbed some serious depths.'

'This is a new low. This terrible circumstance is not fodder for Question Time,' Ms Sanderson fumed.

'This is purely seeking to politicise what is a terrible event, madam speaker ... and a grubby attempt by the Leader of the Opposition.'

Aliyah's mother Jess Yugovich has since slammed the minister for trying to avoid the question.

'The way she behaved is childish and inappropriate,' Ms Yugovich told the West Australian .

'Our lives have been completely destroyed by this, and to see the person who is meant to be helping people like us behave like that is infuriating.'

Ms Yugovich said minister combative response was the first time she had heard Ms Sanderson mention her daughter.

'Libby Mettam asked a valid question, and I want answers to those questions,' Ms Yugovich said.

Ms Sanderson apologised to the family on Wednesday but maintained that Question Time was an 'inherently political forum'.

'I want to start by extending my sympathies to the Yugovich family,' she said.

'It saddens me if any of the comments in Question Time yesterday upset them, and I genuinely wish them well.'

'I continue to say that parents should always be heard, and this is a complex investigation that needs time to be undertaken.'

Ms Yugovich hopes to meet and sit down with the minister, along with a commitment to towards ensuring similar tragedies are avoided in the future.

A coroner's findings into the case are expected to be handed before Christmas.
