The whole "Well, in EUROPE they....." argument bugs me. Newsflash: WDW isn't in Europe. It's in the US and here, letting your hoo-hoos hang out on Main Street in MK under the pretense of "nursing" when a kid's mouth is only attached to ONE of them is not accepted by the majority of our society.....Especially the ones who have taught their kids that certain body parts are private and not to be shared with 70,000 of your closest friends.
My sister nursed three kids and in public at that. No one ever had a clue. She never flashed even one of her girls, let alone had the spare one hanging out for all the world to see. When I go to Europe and I enter a cathedral in certain countries, I cover my head. In Russia, I take off my shoes when I enter someone's home. I do my best to follow the social customs and not pull the "Well in AMERICA, we ........" Because I'm not IN America.
Well, when you're in the big middle of MK, you are not in Europe or any place other than the US, and it's common courtesy to follow the social customs here. That means NOT letting your breasts hang out when at least one is not even serving a purpose. Slap a kid on the other one, keep it occupied and I'm good.
