"She denied calling (the child's) doctor before deciding to give the baby the controlled substance," the documents said.
Pickerd told investigators she gave the baby Narcan when she found her unresponsive and realized she was overdosing on the drug.
Methadone is an opiate typically used to wean addicts off narcotic pain medication. Narcan is a drug that is administered to people overdosing on opiates.
The infant girl was hospitalized for several days, ABC13 reported.
“The baby was released from the hospital on Oct. 5 after going through detox for methadone,” Sgt. Catherine Williams with the Grand Rapids Police Department said.
The girl has been placed in the custody of Kent County Children’s Protective Services, ABC13 said. A hearing has been set for later this month to terminate Pickerd’s parental rights.
