The backlash began after Martha shared sponsored social media content featuring her three-year-old son, Lucius, interrupting her while she was filming. In the clip, Martha appeared to lose patience and told him to leave the kitchen.
The moment quickly split viewers. Some criticised Martha's response and accused her of being too harsh, while others defended her and said the reaction to a short clip was unfair.
According to news.com.au, Martha later responded with a sarcastic follow-up aimed at the online "perfect parents" who had judged the moment.
The former MAFS star shares Lucius and baby daughter Sunday with Michael Brunelli, who she met on the 2019 season of Married at First Sight Australia.
Martha has often been candid about parenting and family life online, which has made her a frequent target for both support and criticism. This latest reaction shows just how quickly reality TV alumni can become the centre of a debate that has little to do with the show itself.
It also raises a familiar social media question: how much can viewers really judge from a brief parenting moment filmed for content?
For Martha, the answer seems clear. She is not letting strangers online have the final word on her family.
