The former Miss Universe Australia took to Instagram to share the news about Violet, 4.
"One of those challenging days as a parent.. The love we have for our children is beyond words," the 30-year-old captioned a photo of her eldest child and husband Michael Miziner.
She continued, "This morning before Violet went into surgery. I noticed a small bubble pop up on her groin area which turned out to be a hernia. Lots of cuddles & snuggles for us this weekend. 💗"
Sending love to little Violet!
