Jasmine Norman pleaded no-contest to a felony child neglect charge.
Back in February, police say the baby was sitting in a bouncy swing with a bag over his head.
Norman says she doesn't know how the bag ended up over her son's head.
Medical examiners were not able to figure out how the baby died so they left the cause of death as "undetermined."
Most of Norman's ten-year sentence was suspended.
