Nixzaliz Santiago, who was convicted of manslaughter in the death of her 7-year-old daughter, Nixzmary, will not be sentenced until next week, law enforcement officials said.
Santiago was due to be sentenced Wednesday.
The death of Nixzmary made national headlines and the case hastened reforms in New York's troubled child welfare agency.
Nixzaliz Santiago was convicted in October in the 2006 death of her tiny, malnourished daughter. The girl was being severely punished when she was killed, prosecutors said.
She faces up to 33 years in prison.
Santiago's husband, Cesar Rodriguez, was convicted of manslaughter in March for delivering the fatal blow. Prosecutors alleged he was behind much of the abuse the young girl endured. He is serving 29 years in prison.
Evidence in the case included crime scene photos from the room where Nixzmary was bound to a chair, starved and forced to urinate in a litter box.
