A daycare in Oklahoma is under investigation for giving children Benadryl to help them go to sleep.
Employees have come forward, saying they were instructed by the owner to give the Benadryl.
The drug can cause small children to stop breathing and should not be given unless instructed by a doctor.
None of the seven infants identified were injured.
According to police, a former employee contacted the Department of Human Services.
The daycare cannot open again until officials have completed their investigation.
