A man jailed over the manslaughter of his stepson claims the boy's own mother waited hours to seek medical attention when the boy fractured his arm because she was buying drugs.
Matthew Scown was jailed for four years over the tragic May 2009 death of four-year-old Tyrell Cobb.
Tyrell's mother Heidi Strbak is being re-sentenced in Brisbane Supreme Court for her role in the manslaughter after she successfully appealed her nine-year sentence.
Scown on Wednesday told the court that just weeks before Tyrell's death, he suffered a nasty fall at daycare and Strbak was called to pick him up.
He was clearly in a lot of pain, but rather than rush to the hospital, Strbak kept Tyrell at home so that she could 'score pot', the court heard.

'I made a sling from a pillow case (for Tyrell),' Scown said. 'I thought it was a bit weird.'
Scown testified that he tried to encourage Strbak to take Tyrell to a doctor, but that she refused because she needed marijuana and her drug dealer wouldn't be available later in the day.
He said he called Jason Cobb, Strbak's ex and Tyrell's biological father, to help sway her, but that it only made her angrier.
Strbak interrupted the phone call and hung up on Mr Cobb, the court heard.
'I think scoring pot or taking your son to the doctors is a no-brainer,' Scown said.
The court also heard that Strbak was violent toward Tyrell in the days leading to his death on May 24, 2009.
Scown claimed that he witnessed Strbak hit him across the face at the dinner table the day before his death, causing bruising under his eye.
He claimed that she was angry that Tyrell had vomited at the dinner table.
On another occasion, Scown claims Strbak struck the four-year-old across the side of his ribs.
'She just marched him to his room and smacked him... on his right side,' he said.
After his death, Strbak pleaded guilty to Tyrell's manslaughter.
Medical officials determined he died from blunt force injuries to his abdomen which had caused a leakage to his stomach and internal bleeding.

Strbak, who remains in custody, will be re-sentenced over the evidence heard during this trial
Scown was sentenced to four years behind bars for his role in Tyrell's death, but walked free from sentencing after already serving two years and eight months behind bars.
He found himself back in custody in early 2019 after committing close to 30 drug and fraud related offences, breaching the sentence.
He was released again, but the court heard that he is in jail again after breaching parole in October and failing a drug test.
The court heard that he is due to be released in January.
The Brisbane Supreme Court is hoping to determine whether Strbak or Scown inflicted the final blow which cost little Tyrell his life.
Strbak, who remains in custody, will be re-sentenced over the evidence heard during this trial.
The trial continues.
