THE BRONX - Charges have been upgraded for a Bronx mother and her boyfriend accused in the death of her 3-year-old daughter.

Sherika Stewart and Leon Walters are now facing manslaughter charges after Ahnya Louis-Hardy was found unconscious in Stewart's Manhattan College Parkway home last month.

Police say the 22- and 25-year-old admitted to striking the toddler with a belt because she refused to do her lessons.

Stewart and Walters were originally charged with assault and reckless endangerment.
