I haven't had time to read even most of the posts beyond page one, but had to respond.
Throughout the many countless of times I have been in the company of nursing mothers (which I have been one of for sometime now), I have seen many different nipples, white skin around the breast, chocolate skin around the breast, tummy fat rolls, skinny ribs, lumpectomy scars, etc. See my point here? I have seen "more" than those wanting us to cover up want people to see.
And each and every time I have seen these mothers nursing, I see love and I see a feeding time for baby (or toddler, etc!), a special time for mom and child. I have seen women that weren't the least bit shy about what may get seen, and others that were, but kept at it anyway, regardless.
I have yet to witness a woman deliberately unrobe, yank both breast out, squirt passerbyers with milk, or any other such things
It is such a simple act, and I will never understand all the hoopla around it. If those that are so troubled by it could see it "in real life", would their minds be changed?
