Judge Margaret Deglau scheduled an April 4 trial for Susan Lambert Hoback-Tweardy, 43, and ordered her not to have any contact with the juveniles who are the subject of the charges against her.
Deglau made an exception for Hoback-Tweardy's sons after the defendant told the judge that the two were among the 19.
Hoback-Tweardy was ordered not to use any alcohol pending the trial. She faces a maximum punishment of up to 12 months in jail on each charge.
She appeared in court without a lawyer but said she plans to hire counsel.
Hoback-Tweardy was arrested Tuesday after police were summoned minutes before midnight Dec. 31 to a residence in the 200 block of Middle Quarter Lane south of River Road near the Country Club of Virginia's James River golf course.
It was not clear why charges were issued nearly two weeks after the incident.
Police said medical units were called to the scene because of concerns about the inebriated condition of the some of the juveniles.
