In Australia, a woman is legally allowed to breastfeed her child wherever, whenever and however she wants or needs.
The law does not say she must put a blanket over the baby's head. It does not say she must shut herself into a private cubicle in the annals of a shopping centre. It does not say she may only feed when there is no risk of offending the delicate sensibilities of a society that worships the underwear model but cannot seem to cope with a breast being used to nurture rather than titillate.
She may feed her baby as needed, wherever that may be.
If you take issue with a woman breastfeeding in public, that is exactly what it is. YOUR ISSUE.
That is all.
