The families of child killer Beverley Allitt's victims say they are relieved that her sentence has not been cut.
Allitt's minimum jail term was confirmed at 30 years
Allitt, convicted in 1993 of four murders, had her tariff fixed at 30 years at the High Court.
Joanne and Chris Taylor, the parents of Allitt's first victim, seven-week-old Liam Taylor, said they were pleased with the judge's decision.
Mrs Taylor, of Grantham, Lincolnshire, said the judge's comments touched on the suffering of all the families.
Mrs Taylor said: "That's what we are here for - not just my child. He [the judge] couldn't have done any more. He's done the best he can."
Liam, who was admitted to hospital with breathing difficulties, had a number of unexpected collapses, at all of which Allitt was present alone.
The prosecution evidence was that it was impossible to determine the precise cause of his February 1991 death - whether it was the result of suffocation or the injection of a drug.
David Peck, of Newark, Nottinghamshire, the father of 15-month-old Claire who died in March 1991, said: "I'm absolutely delighted with the outcome - and pleased for the other families as well."
Claire, who suffered from asthma, was admitted to hospital and collapsed when Allitt was alone with her.
Allitt was convicted of her murder after the jury heard prosecution evidence that the toddler had been injected with potassium and lignocaine.
Mr Justice Burnton said that during an eight-week period in early 1991, Allitt killed, attempted to kill or seriously harmed 13 children in her care on the ward.
"The evidence at her trial suggested that she suffocated some of her victims and injected air or drugs into others."
He said: "The impact of these offences does not require to be described and could not be exaggerated.
"Young lives were cut short at their inception. Patrick Elstone's life and that of Katie Phillips have been grievously damaged.
"The offences to the children took place in what should have been, and what their families must have believed to be, a place of safety; the offender made it into a place of extreme danger."
The effect of the offences on all the families "must have been terrible".
He added: "Each of the offences is an immense personal tragedy for the family concerned. They received a life sentence from which there is no remission, no release on licence."
