Kyle Kitchen, 38, of no fixed address, “never showed any remorse” after his temper left his daughter Primrose Kane unable to walk or talk, dying six months later.
He was sentenced at the Old Bailey to a minimum of seven years and eight months in prison after being convicted of murder on March 12.
Kitchen was already serving the 15-year sentence he was given at Blackfriars Crown Court in August 2016 when he was convicted of two counts of grievous bodily harm.
In a trial from February 10, the court heard Primrose’s mother and father contacted NHS 111 after the two-month-old was found unresponsive at home at Queens Crescent, Camden on November 3, 2014.
Doctors found Primrose suffered such severe injuries to her head, including a skull fracture and bleed on the brain, that she would grow but remain with the mental capacity of a baby.
This included severe physical and developmental disabilities and developed into cerebral palsy and scoliosis, leaving her unable to communicate and suffering with chronic pain.
While Primrose was being treated in hospital, the Met’s Child Abuse Command team launched a criminal investigation after deeming the injuries not to be accidental.
Both her mother and father were arrested and later convicted.
Primrose died aged six on May 17, 2021, at the home of her grandmother in Welling.
Doctors concluded Primrose had died from pneumonia caused by profound neurological, physical and developmental disabilities.
Homicide detectives were informed Primrose had died and decided whether the assault in 2014 contributed to her cause of death.
Kitchen was arrested and charged with murder following a Met Specialist Crime Command investigation.
He was convicted at the Old Bailey on March 12.
Detective Inspector Laura Nelson, from the Met’s Specialist Crime Homicide Team, said: “Primrose was born a happy and healthy baby.
“The reason why Kyle Kitchen lost his temper and shook his daughter remains unknown.
“However, his actions have resulted in Primrose’s short life being lived in pain.
“No child should ever have to suffer in this way.
“The fact that such serious injuries were caused by her father makes this case all the more shocking.
“At no time, since 2014, has Kitchen shown any remorse for his actions.
“As a team, we have fought hard to bring justice for Primrose, whilst others close to her have been in denial about how the assault in 2014 occurred.
“Today’s sentence will bring some closure to Primrose’s family, but this will never compensate for their loss.”
