Comedian Arj Barker asked a mother to leave his show at the Melbourne International Comedy Festival due to her baby's crying.

The mother, Trish Faranda, contended the baby was not excessively loud and was making typical baby noises.

Barker justified his request by citing the need to ensure an enjoyable experience for the audience and the show's age recommendation of 15+.

The incident prompted some audience members to walk out in support of the mother and attracted criticism from politician Ellen Sandell.

The festival's policy permits infants but expects parents to manage noise by sitting at the back and leaving if necessary.

A social media debate ensued about the balance between accommodating parents at events and ensuring performers can deliver uninterrupted shows.

Both parties involved in the incident, Barker and Faranda, expressed regret over the disruption it caused.
