Detectives with the Chittenden Unit for Special Investigations charged Rosemary Gile Wednesday in the July death of her four-week-old son, Saunder Gilruth.
Emergency responders responded to Isham Street in Burlington on July 22 and rushed the infant to Fletcher Allen Health Care (now the University of Vermont Medical Center), where he died on July 30.
Gile is charged with involuntary manslaughter in the death. She is due to appear in court on Dec. 4.
The death was one of a string of child deaths this year that spurred calls for reform in the Department for Children and Families, which is responsible for protecting the state's youth.
