I've seen a lot of negative comments and attitudes about using a cover when you NIP. I have DD's. I know that there are Moms here with much bigger breasts, so I can't even immagine what that's like.. My point is, with large breasts, it can be very challenging.
There are times when I don't need a cover. But, when my DS is fussy, or distracted, NIP can be very hard. I'm not posing in Playboy and I don't want anyone seeing my breasts. It's not that I feel ashamed of my body, or that I feel like I'm being nice to other people by covering up. I just feel more comfortable when everyone isn't seeing inches of my breast.
I don't think that NIP is indecent at all.. But when the conventions of society is that BFing is a private activity, I don't think that using a little disgression is a bad thing.
I've heard stories of Mamas nursing very openly, not attempting to be disgreet in the least, and flashing tons of skin. While it's your right to feed your baby where you need to, at the same time I don't think that you should make a public display out of it.
The more you shove it down everyone's throat, the more resistant to it they become. If you share it in a gentle manner, people are much more open minded about it, and you gain more thorough acceptance from those who are so strongly opposed.
That's just my opinion. I see BFing like any other strong belief in my life. Vegetarianism, Religion, Circ, AP, CIO, Education, Drug Law Reform, etc. If you make it a "I'm right, you're wrong, and that's that" battle, you'll turn people off. If you make it a "Well, this is what I do because it works for me, and this is the medical evidence that backs it up, and look at this beautiful and healthy little baby who is 7 months old and hasn't even had so much as the sniffles" conversation, then there will be people who take something good from it, and sway their opinion just a little more to the left.
Love and Peace!
