Who cares? Is there a rule that someone has to nurse a certain way? No, and why does your husband have to leave the room? Surely he is a grown man who can handle seeing a boob. I don't know just seems childish to me, there should be no shame in nursing however a mother chooses.
I would keep my mouth shut.
