An embarrassed father left a shopping centre parents' room with his naked son in his arms after a woman declared the room was "only for mothers" and told him to "get out you sicko", according to a second mother who witnessed the exchange.

Tamika Ives said she came to the man's defence, bringing him back to the change room where he had left his belongings and told the abusive woman that she would "100% back the dad up" after the attacker threatened to call security.

The 18-year-old posted about the incident on Facebook and was shocked by the number of people who had seen fathers face similar situations.

Ms Ives said she shared details of the incident on the Sunny Coast Community Board Facebook group after witnessing other women staring at fathers in parents' rooms and mumbling rude comments under their breath.
