No. Mine looked the same before and after. (Just about a cup size larger, but also I was about ten pounds heavier for a couple of years after my son was born.) If anything changes the appearance of the breasts, it is pregnancy, not breast feeding.
I didn't breastead my first as he refused it and they did change due to pregnancy. I fed my other two and there were no other changes other than size. They have got 2 sizes bigger with each pregnancy lol.
