Chao-Huei, There are not really laws in the US AGAINST breastfeeding in public, but there are obscenity/indecency laws that are sometimes incorrectly applied to breastfeeding mothers. Many states are now passing laws to make sure that this does not happen. New York, my state, went further. New York's law made breastfeeding a civil right, and provided for fines or prison time for anyone interfering with a woman breastfeeding anywhere she has the right to be, even if her nipple is exposed. Hope this helps. -- Catherine Watson Genna, IBCLC NYC [log in to unmask]
