The parents accused of giving a 10-week-old baby girl half an ecstasy tablet took the infant home from hospital after facing court.
The Victorian couple, from Gippsland and holidaying in far north Queensland with friends, were freed on bail after appearing in Cairns Magistrate's Court charged with grievous bodily harm.
They stood accused of giving the girl part of an ecstasy tablet, causing violent fits which nearly killed the infant when her heart stopped on Sunday.
The girl was taken to Cairns Base Hospital in a critical condition and placed in an induced coma in intensive care.
The father, 24, and mother, 22, who cannot be identified under Queensland child protection laws, appeared in court yesterday with their heads bowed and visibly shaken.
The young mum fought back tears as she faced the magistrate but neither of the pair was required to plead and they said nothing as they stood charged with one count each of grievous bodily harm and possessing a dangerous drug.
No details of the case were read out to the court by the police prosecutor.
Police would allege it was a "negligent" and "not a deliberate act", a Queensland police spokeswoman said outside court.
Magistrate Rob Spencer excused the couple from attending their next committal mention on February 3. Dressed neatly and trying to hide their faces, the couple fled court and returned to the hospital where they had maintained a vigil by their daughter's side.
They were interviewed by Child Safety officers before the child, who is reportedly in a stable condition, was released from hospital into their care.
Queensland Child Safety Department director-general Norelle Deeth last night defended the decision to let the child return to the couple.
She said she was unable to discuss specific cases.
But, she said: "The safety and wellbeing of a child is the number one priority for the Department of Child Safety.
"In making assessments such as these, the department consults with inter-agency professionals including police, pediatricians and other health experts.
"These professionals inform the department's assessment of the potential future risk of harm, taking into consideration the particular circumstances surrounding a matter.
"In cases such as these where families reside in other jurisdictions, the department will work closely with other relevant agencies to ensure the safety of the child and will provide support to the family."
Paramedics went to Behan St, Manunda, about 10.30am on Sunday, about 90 minutes after the baby suffered a seizure.
