NIP is definatly a leanred skill.
I found with DS1 the more praticed he and i became the less i even NOTICED if I was in public

at some point, nurseing at home, at mom's, at church, meeting the Pastor in his office (with DH), at the sotre, while walking the Freedom Trail in Boston, at The Old North Church, on a plane, on a train, in court .... it all blurrs together.
I know i got to a pint i never even thought about 'how am I going to nurse here" I just did it ..... compnay picnics, while cooking, walking around malls or hainv lunch with Scott's boss..... a personal fav of mine was a gun show where i swear i was the only female much less the only mother, wedding, funerals, building sites ....
I have found the more confident you are, the more natural you are, the less other notice. 1. i don't think people generally notice that much anyway - i think it is "pimple on Prom night" YOU think eveyoine is noticeing cuz you are not at ease and 2. the more at ease you are the less you draw attention to yourself and 3. the more confident you are in any part of your life, the more natural you feel, the more confidnce you put off and the more people accept it -- remember the first time you were big enough to wear high heels??
Personally I do NOT cover -- unless feeding in a carrier and the carrier is a de facto cover, not intental ..... 1. Theo HATED to be covered and would fight, cry and not nurse and cause a much much bigger stir if i tried

and 2. I think the cover draws more attention than the baby and nurseing ... getting something (blanket, shawl, cover) out, get baby in place, moving clothing, getting the baby latched, getting it all settled .,..... I feel that just calmly putting baby to breast, moving some clothes and feeding baby -- and when you are praticed you won't even look down

is much less "drawing of attention" JMO.
I suppose I might cover in a few situations (if we were touring churhes in Italy again) .. but then I would just wear the babe in the sling and let that cover for me ... nothing special.
But I appercitae anyones level of confort -- just be sure it is for YOU and not for theose around you -- really or in your own perception of how they will react.
It is your legal right, and it is your baby's birth right.
Pratice, pratice, pratice.
I am not as quick and easy with C yet as I was with T ... but i am better now with C than I was with T at 6 week ..... it is all a learning curve.
