The man, who isn't named to protect the victim and their children, appeared in Wodonga Magistrates Court earlier this month to plead guilty to recklessly causing injury.

He was jailed for four months over the offence which magistrate Ian Watkins labelled "too serious" not to send him to jail.

Police prosecutor Leading Senior Constable Penny Lawler said the man, 30, returned home after drinking with a friend at around 12.35am on May 7, 2020.

"The accused and the victim had an argument in the backyard where he attempted to punch the victim, but missed," she told the court.

"The arguing continued in the main bedroom when the accused punched the victim three times to the head, she sustained swelling and bruising."

The court heard the victim tried to run away from the man.

"The victim picked up their one-year-old child in the bedroom," Leading Senior Constable Lawler said.

"At this time the accused heard the police knocking at the door, he hit the victim on the head with a glass bottle and blood dripped onto their son."

The court heard the man had made every effort since the offence to seek help and will be placed on a 12 month community corrections order once he is released.

Mr Watkins told the man he had consumed "far too much alcohol" at the time of the offence.

"Mercifully there wasn't serious injury, but there definitely could have been," he said.

"You may form the opinion that your child is too young to remember this.

"But children can remember trauma for the rest of their lives. This is too serious not to send you to jail."
