Natasha King, 24, will be allowed to post $500 cash and $1,500 surety as she awaits a trial setting on the misdemeanor charge.
King and her co-defendant Billy Reilly were charged earlier this month.
Witnesses said they allowed the two-year-old to ingest the drug. Bond was set earlier at $5,000 for Mr Reilly. By Tuesday morning, both suspects remained in custody in the Buchanan County Jail.
