Lynija Eason was arrested on Saturday and charged with 2 counts of endangering the welfare of a child.
This comes as the death of the young girl remains under investigation.
Police say Jalayah Eason died Friday after she arrived at the hospital with bruising all over her body. An autopsy will determine her cause of death.
Eason's mother called 911 just after 4 a.m., reporting the injuries.
Police responded to the Forest Houses on East 165th Street in Morrisania and found the child unconscious in her mother's bedroom.
Authorities say she had bruising and trauma on her wrists and torso.
Jalayah was taken to NYC Health + Hospitals/Lincoln where she was pronounced dead.
Detectives are questioning her mother but no charges have been filed, and the cause of the girl's death will be determined by the medical examiner.
The girl had been living in a squalid 12th floor apartment that was filthy and filled with clothes and other belongings strewn about.
A downstairs neighbor said she often heard crying from the apartment above.
