A Queensland father poisoned his baby daughter with anti-psychotic drugs and forced her to swallow a ten cent coin, police allege.

The 19-year-old unemployed man, who cannot be named, has been charged with attempted murder and was granted bail in Brisbane Magistrates Court on Thursday.

Police said his partner woke late on August 13 to find the couple's four-month-old daughter struggling to breathe.

She had turned blue and was "pale and floppy" with a temperature of just 34 degrees, according to an affidavit tendered in court.

The infant was taken to hospital from the family's Morayfield house, north of Brisbane, just after midnight.

Hospital staff noted she had a high heart rate and would scream in bouts.

A urine test found the antipsychotic pericyazine and the attention deficit disorder drug methylphenidate.

The father was on both drugs and suffered attention deficit disorder, bipolar disorder and schizophrenia.

In hospital the infant vomited up a ten cent piece, which doctors said she could not have ingested accidentally because she lacked the motor skills.

A day earlier the father had asked his partner and her parents what would happen if the child swallowed a coin and was told she would die.

He had an argument with his partner the night of the incident and had been the last to feed the baby around 11.30pm, according to the affidavit.

Police opposed bail, saying the man had a propensity for violence and was a risk to himself and others.

Legal Aid lawyer Rhianna Batt said he had mental health issues but no significant criminal history that indicated a risk.

She said he had the support of his mother, two sisters and disability advocates, who were all in court.

Magistrate Judy Daley said she was comforted by the man's support network and did not believe he was a flight risk.

She granted bail on the condition he have no contact with his daughter or partner and that he would stay away from the Morayfield address.

The man has also been charged with use of a controlled drug, possession and stealing.
