Until you’ve been a breastfeeding Mom and been engorged and needed a way to express milk for you baby you have no room to talk or judge. Just because she doesn’t have a baby with her doesn’t mean she doesn’t need to express milk for that baby. Her breast pump may have gotten checked or needed a plug to work off of and this was her only option. Im a breastfeeding Mom and if I need to pump or feed my baby I will NOT be doing it in a bathroom and most certainly not in one of those tiny airline bathrooms. Want your meal prepared in a bathroom or be forced to eat in a bathroom? I know I wouldn’t!
