Why don't you eat YOUR meal in the bathroom? If you're offended by a mother discretely breastfeeding her child, you've got issues.
I am amused by the strong suspicion that if they proved breastfeeding enabled the male to retain or regain erectile function you'd get whiplash watching the attitude reversal of most such Victorian posters.
No kidding. I have not been much into public breastfeeding because I am too shy, but I have had to resort to it from time to time (very well covered). Nursing in the bathroom is sick and dirty.
