I am still BFing the Budgie, who is now 18 months, and I BFd Princess Parrot for three years. Not once did I receive any dirty looks or nasty remarks. As neither of my babies would tolerate wraps or blankies over their faces, I just used to untuck my shirt, or have my special breastfeeding tops on. They both have big heads and nobody could see anything anyway!
One incident I heard of- a friend of mine was part of a mothers' group which used to meet at a local café when their babies were still small. One day one of them was feeding her four month old when the baby pulled off, looked around and hopped back on (as they tend to do). This caused a spray of breastmilk that arced across the room and landed, with pin-point precision, in the cappuccino of a gentleman sitting opposite the group. The entire café was in a horrified hush! The mother then beckoned the waitress over and said, "Please get that man another cappuccino and I'll come and pay as soon as the baby's finished," and everyone continued about their business. It was, and is, no more than an amusing anecdote.
(the mother did say that she'd strongly considered fleeing, but would have had to lug the nappy bag, detach the baby, and she rather liked the café and wanted to go back again).
I must say that I am astounded that a café owner in Australia would ask a mother to stop breastfeeding! It's not exactly a new law, the right to breastfeed whereever! That owner was just making trouble for herself, really.
