Acting Detective Inspector Grant Ralston thanked all those involved in the investigation, which led to the arrest of the woman and her de facto partner.

“This case has been a very sad case to investigate. We are talking about a four-month-old baby,” he told reporters on Saturday.

“I don’t want to go into the specifics of the investigation or the injuries, needless to say they were significant and horrific.”

The woman remains behind bars, although she is expected to apply for bail before her next court hearing date on April 10.

The man will face Beenleigh Magistrates Court on January 14.

Police say the pair have children of their own.

“The other children are safe and well,” Acting Det Insp Ralston said.
