A Missouri mother wants accountability after her 9-year-old son, who has autism, ate handfuls of pea gravel while at school. Candice Whitlow’s 9-year-old son has autism and is nonverbal. She says he needs constant supervision from an aide at his school in the Doniphan R-1 School District. Whitlow noticed Feb. 25 that her son had gravel in his stool after he returned home from school, so she took him to the emergency room, KAIT reports.
