It's ridiculous that we would even be worrying about this in the 21st Century, but the state legislature passed a law today that protects breastfeeding mothers from being arrested for indecent exposure. The governor is expected to sign it. Theoretically, up to now, women could be forced to register as sex offenders for feeding their children (if arrested and found guilty).
American society is still prudish in many ways, with language or nudity controlled to various degrees on TV, radio and at the cinema. We should have long ago shaken off our silly mores.
Also, breast milk is what babies are supposed to be nourished on, though unfortunately the market economy has created products that even take the place of that.
