The senator made headlines earlier this year when she became the first person to breastfeed in the Australian parliament – and today she went a step further, breastfeeding her new baby, Alia Joy, while successfully moving a motion on lung disease.

Waters told BuzzFeed News she had to breastfeed while giving the speech because, "black lung disease is back among coal miners in Queensland and Alia was hungry".

The senator said she hopes her decision sends a message to other young women that they too belong in places of power, including parliament.

"Women have always worked and reared children, whether that work was paid in the workplace or unpaid in the home. I hope [this] helps to normalise breastfeeding and remove any vestige of stigma against breastfeeding a baby when they are hungry."
