Alia Joy Waters is just weeks old. But she has already made political history in Australia by becoming the first baby to be breast fed in the Australian parliament.

Senator Larissa Waters returned to parliament today for the first time since giving birth to her second daughter earlier this year, bringing Alia Joy with her while she voted.

And when her baby needed it, she didn't hesitate to feed her.

Afterwards, she wrote on Twitter: "So proud that my daughter Alia is the first baby to be breastfed in the federal Parliament! We need more #women & parents in Parli."
