The woman describes being outraged after witnessing a father she said was being abused by another mother at the Kawana Shoppingworld on the Sunshine Coast for changing his son's dirty nappy.
'There was a dad in the middle of changing his son's nappy, already having a difficult time with his son not wanting to be changed,' Mikaa Ives wrote on a local parenting Facebook group.
The post, in part, reads: 'The lady piped up and started abusing the dad for being in the parents' room: 'It's only for mothers, get out you sicko.''
Ms Ives said the woman, who accused him of 'staring at her kids', threatened to call security on the dad if he didn't leave the room.
The post describes how the young boys nappy was not clean when the pair were kicked out, and they became distressed by the confrontation.
'His son was hysterical and he's just saying 'it's okay mate, we'll go back in there soon.'
Ms Ives says she called the man back in to finish putting a clean nappy on the child and told him if the other woman ended up calling security, she would back him up.
'I was absolutley shocked that the poor bloke felt he had no choice but to leave like she said...I was BEYOND disgusted.'
Other Sunshine Coast fathers have defened the man, sharing similar stories of abuse why've endured when trying to change their children's nappies.
'I'm a dad and copped the same whenever I had to change my son's nappy. Didn't move just told them to [do] whatever they needed to do to feel better about themselves.' one dad wrote.
Another added, 'As a single dad I have experienced this on the coast too many times. Thank you for standing up for this guy.'
'When someone kicks you out of a parents' room you literally have no where to go with your children, it's good to know here are people out there who care.'
