Investigators say Swartz gave her 2-year-old son Beau cocaine when he was visiting her.
She's also been accused of abuse in the past. The boy allegedly suffered a serious injury while in her care in July.
Beau is now in the custody of her father and will spend a lot of time with his grandparents.
Swartz is due back in court Jan. 4.
