Alexander McMultan (29) assaulted both teens when they intervened amid an argument between him and his then partner.
McMultan, 35 Parkhall Drive, Maddiston, appeared at Falkirk Sheriff Court last Thursday, having pleaded guilty to acting aggressively towards a woman, arguing with her and pushing her on the body on March 11.
He’d also admitted attacking a man by repeatedly punching his head and body and striking the 13-year-old on the head to his injury.

Procurator fiscal depute Sarah Smith told the court trouble began brewing in the early hours when the argument broke out.
The court heard how an enraged McMultan shoved the woman, at which point the elder teenager went upstairs to “challenge” him over his behaviour.
The arguing continued and moved into the living room where the man eventually stepped in.
Ms Smith said: “The accused then began to punched the witness several times to the face and body and they began to fight with each other.
“The 13-year-old witness then attempted to separate the two. The accused had attempted to punch the first witness and missed, however, he struck the second witness to the left of the head.
“As a result of his continuing behaviour, the witness contacted police who arrived and the accused was arrested.
“The 13-year-old sustained a bump to the head but didn’t require medical attention.
“The accused replied to the caution and charge, ‘He struck me first’ and to the injury, ‘That was an accident’.”
Defence solicitor William McIntyre said McMultan, who has one previous conviction from 2012, believes a “reconciliation is on the cards” between himself and the woman.
Mr McIntyre explained his client “responded very badly” to the row but was now complying with alcohol counselling.
The solicitor added: “He was a victim of a hammer attack when he was young.
“He is on medication from when his mother died. He is a man under a great deal of stress.
“It’s the sort of behaviour he doesn’t want to get himself involved in again.”
Sheriff Derek Livingston placed McMultan under supervision for two years, during which time he must attend alcohol and mental health counselling sessions.
The order is an alternative to custody.
