It is very important to me that my children see the normal biological purpose for breasts. I nurse my children everywhere without a cover and want them to feel comfortable with seeing others do it as well, and they do. Sure, it's nothing to stare down and make a spectacle of, but it should be a normal thing to see. When children's books are full of baby bottles (and toy babies come with bottles), it's even more important to do so, IMHO, to counterbalance a lot of that.
I do agree that some of the posts in this thread are worded a little strangely, but I do agree quite a bit with the sentiment. I was not breastfed, and many in my generation were not, as it simply wasn't the "thing to do" back then, but I think it's an important thing that needs to be brought back into the open and allowed to become a normal thing to see in society.
