Lucy Letby, a British nurse who was convicted of killing seven babies in her care, will spend the rest of her life in prison.
The 33-year-old was found to have killed seven babies while working in a hospital's neonatal unit, as well as attempting to murder six others.
She had been in her mid-20s when the crimes took place, between June 2015 and June 2016 at the Countess of Chester Hospital, and is the UK's most prolific child killer of recent times.
Letby did not appear in court for her sentencing but was handed a whole-life order, meaning she will die in prison barring very exceptional circumstances, per Sky News.
The judge told the court that Letby "relished" being in the intensive care unit and targeted twins and triplets, particularly those with "uncommon" complications.
Mr Justice Goss told Manchester Crown Court: "There was premeditation, calculation and cunning in your actions."
He added: "The impact of your crimes has been immense. Loving parents have been robbed of their cherished children. You have caused deep psychological trauma."
The judge stated that "lifelong harm" had been caused to the families by Letby cutting short the babies' lives "almost as soon as they began".
Letby had reportedly taken opportunities to harm the children in her care while staff were on breaks, taking advantage of the fact people would not suspect a nurse of deliberately trying to inflict harm.
Mr Justice Goss added in his remarks: "You acted in a way that was completely contrary to the normal human instincts of nurturing and caring for babies and in gross breach of the trust that all citizens place in those who work in the medical and caring professions.
"The babies you harmed were born prematurely and some were at risk of not surviving but in each case you deliberately harmed them, intending to kill them."
The mother of a premature baby identified as Child D said finding out her baby was murdered by a nurse in hospital was "like something out of a horror story", adding that her funeral was held the day before her due date and that the newborn's organs could not be donated as a post-mortem had to be performed.
The mother of Child E and Child F, who were born after grueling courses of IVF, added: "No children in the world were more wanted than them."
Letby had been found guilty by a series of partial verdicts which were delivered several days apart, with reporting restrictions applied by the judge until the end of the trial.
She was found guilty of six counts of attempted murder, including two involving the same infant. Letby did not take part in any of the hearing, and the court did not have the power to force her to attend.
