Chen first appeared at Christchurch District Court on December 4 where she was granted interim name suppression and remanded on bail.
She was back in court this afternoon for a brief appearance.
Defence counsel Phillip Allan said there would be no application to continue interim suppression of name.
The lawyer said Chen also pleaded not guilty to both charges and would challenge the allegations at trial.
Judge Michael Crosbie confirmed that suppression would now lapse.
He remanded Chen on continued bail until March 17 for a case review hearing. A trial date will be set later.
The boy’s father Michael Steele earlier told the Herald that little Kevin was “a dear wee soul”.
He said his life had been a living hell since learning of Kevin’s sudden death, having seen his son just days earlier.
