A baby girl who has become Australia’s most premature baby, being born four and a half months early, is now “thriving”.

Jake and Bree, from Perth, Australia, were on a flight to Queensland for a family holiday when things took a dramatic turn.

Bree had unknowingly caught an infection that caused her to go into labour early. Baby Stevie was born at just 22 weeks and 2 days’ gestation, becoming the youngest premature baby ever in Australia.

“Trying to hold her in just meant crossing my legs and holding on for dear life, and nothing was going to happen,” Bree said.
