To recap some of the judge's comments just before he passed sentence, he noted that for the offence of murder, the sentence is fixed by law and is imprisonment for life.
"You are now 33... I have to determine whether the seriousness of the offences is sufficiently high that I should not make a minimum term.
"These are offences of very exceptional seriousness," he said.
"This was a cruel, calculated and cynical campaign of child murder involving the smallest and most vulnerable of children... you created situations so that collapses and causes of collapses could not be obvious.
"You checked up on parents... there was a deep malevolence bordering on sadism... you have no remorse... there are no mitigating factors... the offences are of sufficient severity to require a whole life order."
He then said: "I sentence you to imprisonment for life. Because the seriousness of your offences is exceptionally high, I direct that the early release provisions do not apply. The order of the court, therefore, is a whole life order on each and every offence, and you will spend the rest of your life in prison."

Judith Moritz
Inside the courtroom

He says at the time, the clinicians thought he'd died of a different condition.
The following night, the judge says, she turned her attention to his twin brother, and added insulin to his feed. "It was not noticeable," he adds.
"You infused a bag that was hung, and several other stock bags so that when they were changed he continued to have insulin.
"Baby F recovered but has severe learning difficulties. No doubt you were reassured that no one suspected insulin had been added, and you went on to attack another baby in the same way eight months later."
