A judge sentenced 45-year-old Heather Reynolds on Tuesday to life in prison with no possibility of parole.
A jury delivered that guilty verdict in July following a nine-day trial.
Reynolds was convicted on charges of murder, possession of methamphetamine and endangering the welfare of a child.
Back on May 10, 2018, Gloucester Township police responded to a call of an unresponsive child on a lawn near a home in Sicklerville.
The 17-month-old child, Axel Reynolds, was pronounced dead a short time later.
The medical examiner's ruled the cause of death to be asphyxia and the manner of death as homicide.
"We are grateful to the jury for the time and attention that they gave to this case," Camden County Prosecutor's Office Homicide Section Chief Peter Gallagher, who represents the state, said in a statement.
