A 27-year-old Carson City woman has been arrested on suspicion of child neglect.
Sheriff's deputies say they found Sheyanne Moore 3-year-old son wandering alone in the area for the third time this month.
Moore, a certified nursing assistant, was booked into jail Thursday on a gross misdemeanor charge.
She had been warned by officers twice before that she would be arrested if the boy was found wandering alone again.
Investigators say Moore told them that she sleeps during the day because of her job, and that she could not afford a sitter.
The boy has been turned over to his grandmother.
