Jay Dixon, 22, from Dundee, carried out a series of cruel acts on a four-week-old boy while controlling and degrading the child’s mother.
A nurse noticed extensive bruising on the infant, triggering an investigation which exposed Dixon’s criminal behaviour.
The High Court in Stirling heard that Dixon’s actions included trying to drown the baby in a bowl of water, throwing him so high that his head hit the ceiling and pushing hard on his chest in an attempt to make him stop crying.
He subjected the child’s mother to violent and coercive behaviour, threatening to kill her and the baby.
The court also heard that Dixon admitted assaulting, controlling and abusing another woman during the course of a short relationship.
Having pled guilty to a total of four charges at a hearing earlier this month, Dixon was today given an extended sentence of 10-year and three months with six years and 3 months in custody.
Non-harassment orders, banning Dixon from contacting or attempting to contact the victims, were also granted.
Moira Orr, who leads on major crime for the Crown Office and Procurator Fiscal Service (COPFS), said society was safer through Dixon’s incarceration.
She said: “Jay Dixon’s behaviour shocks every one of us. He is a danger to women and children.
“A defenceless baby suffered terribly at his hands. Two women endured violence and coercion which has damaged their lives.
“I commend the victims in this case for the courage it took to come forward and report his crimes. They have allowed COPFS prosecutors to ensure Dixon faced justice.
“To other victims of abuse or violence, or anyone who has witnessed such crime, please report it. We all deserve to live in safety.”
