I too have no problem whatsoever with a woman breastfeeding a baby in public, but any woman can do it discreetly. I always joke about the fact that I have Catholic friends with very large families who breastfeed their kids right in front of me and I barely notice because they use a small blanket over the shoulder. It’s not hard.
Both my daughters and my wife did so in public very descretly, never an issue. No one ever went off on them either.
