Dover police say 19-year-old Tiana Harris of Dover, 21-year-old Estefania Myers of Felton and 47-year-old Lisa Parker of Dover each posted $10,000 secured bond after being arrested Monday.
All three are charged with felony assault and conspiracy, as well as several misdemeanor counts of endangering the welfare of a child.
The three were employed by Hands of Our Future LLC Day Care. State officials suspended the day care center's license after authorities obtained cell phone footage of a March incident in which adults allegedly encouraged the toddlers to fight.
