TYRELL Cobb's mother will face a contested sentence next week, taking probably three days.

Brisbane Supreme Court will hear contested facts relating to whether Ms Strbak caused blunt force trauma instrumental in Tyrell's 2009 death.

Medical experts will be called to give evidence.

A post-mortem revealed Tyrell Cobb (above) had 53 bruises and 17 abrasions when he died.

Prosecutors told the court today they want medical evidence to be presented first, before other witnesses testify next week.

Strbak has no prior criminal history.

She is presently on stringent bail conditions including a $100,000 surety.

She may not apply for a passport or approach witnesses.

Defence counsel Greg McGuire accompanied Ms Strbak to and from her arraignment.

EARLIER: TYRELL Cobb's mother has admitted unlawfully killing her son.

Heidi Strbak appeared at Brisbane Supreme Court on Wednesday, more than eight years after the four year-old boy was found dead at home on the Gold Coast.

When arraigned on Wednesday afternoon, she struggled to say the word "guilty".

Former Sunshine Coast and Gladstone man Matthew Scown, previously Ms Strbak's de facto partner, was convicted of manslaughter last month.

Tyrell was pronounced dead on May 24, 2009, shortly after Scown called 000 to say the boy was unwell.

Ms Strbak was released on bail in August 2015.

Justice David Boddice said "significant" issues remained around the facts of the case.

Ms Strbak will be sentenced next week.

Her bail was enlarged.
