Breastfeeding on the cover of a national magazine for the sake of generating prurient interest and increased sales. That's a sickness.
For the record, I nursed both of my children and I too consider it a beautiful, natural, maximally healthy thing that is to be encouraged and accepted. I didn’t deliberately seek privacy or hide myself away, but neither did I flash my equipment around. I just sat down somewhere, slipped my baby up underneath my loose shirt, and let him nosh. No one ever said a thing or gave me a dirty look, no matter what part of the US I was in, even in a few very upscale restaurants in Manhattan.
Women who flash their boobs, sometimes spraying milk around, are exhibitionists. I have no sympathy.
