A father has been sentenced to nine years in jail after being found guilty of manslaughter.
Matthew Jones had been left alone with his 15-week-old baby Cody for no more than an hour at their home in Ebbw Vale, the court heart. At the time, his partner Paula Williams was visiting her sister.
Judge Mr Justice Simon Picken said the 26-year-old, from Aberdare, had not intended to kill Cody, but "lost it" after becoming "frustrated" when he was unable to stop him from crying.
Newport Crown Court also heard how Cody had "older injuries" including a fractured shoulder, broken ribs and a bleed on the brain.
Richard Smith QC, defending Jones, told the court his client had "cared immensely" for Cody before causing his death, and had since shown "genuine remorse".
Cody Rhys Williams-Jones died in December 2016.
