(CBS) NEW YORK - Yoselyn Ortega, a New York City nanny charged with stabbing two small children to death, has again been found fit for trial after asking a judge to reconsider.

A Manhattan judge reaffirmed his finding in Ortega's case Tuesday. State Supreme Court Justice Gregory Carro heard recorded phone calls the suspect made from jail to relatives and determined her to be coherent while discussing everyday matters.

Police say Ortega killed 6-year-old Lucia Krim and 2-year-old Leo Krim in October while their mother was out picking up her third child from a swimming lesson. Authorities say Ortega also cut her throat in a suicide attempt.

She has pleaded not guilty to murder.

Defense lawyer Valerie Van Leer-Greenberg says Ortega's delusions and injuries mean she cannot understand the case.

Doctors have offered diverging views of Ortega's mental state.

On April 5, Carro first ruled that Ortega was fit to stand trial after two mental health professionals found that she could assist in her defense in a meaningful way. The defense challenged those findings and in a competency hearing in June, psychiatrist Karen Rosenbaum testified that Ortega hears voices in her head that talk about killing people.

Rosenbaum also testified that Ortega did not understand why she was handcuffed to her hospital bed or why police were outside her room in the months after the murders.
