"Ended up in the emergency department with Zander today after an ultrasound showed an inflamed appendix..." she shared alongside a video of her brave 4-year-old.
This comes only a month after the former Australian Olympian announced that her daughter Lexi had suffered from a seizure.
"Last night was the most terrifying moment of my life," she started the heartfelt post back in May.
"Our 11 month old, #lexilevett had a seizure, stopped breathing & turned blue..." she continued.
Before she detailed her husband Sam Levett gave their baby girl CPR when she stopped breathing.
"I called an ambulance & talked to the operator... we are still in hospital but out of danger, just waiting on test results as they believe she has a virus which caused her temp to rise dramatically, causing the seizure," she wrote.
"Both Sam & I did an Infant CPR Course when Zander was born & last night, despite the panic, it all kicked back in... so please, if you have children or are around kids often, brush up on your CPR skills, hoping you never need it, but prepared if you do. 🙏🏼 #emergencyroom#infantcpr #worstmomentofmylife#perspective," she advised.
Wishing Giaane and Sam's family all the best.
