The girl bit her nails and looked down during her court hearing Monday in Maine.
Three-month-old Brooklyn Foss-Greenaway was staying overnight in the 10-year-old girl's home in the care of the girl's mother.
The mother called police on July 8 to report that the infant was not breathing, authorities said. The state hasn't released the cause of death, but the baby's mother was told that her child ingested medication and was suffocated.
The state chose not to try the girl as an adult. If convicted as a juvenile, the maximum penalty is incarceration until age 21.
The Associated Press generally does not identify juveniles accused of crimes.
