i generally breastfeed anywhere i need to, but i try to be as discreet as possible because i know - crazy as it is - some people don't think nursing in public is appropriate or they're really uncomfortable with the idea. but just so you know, in california, breastfeeding mothers are protected:
Cal. Civ. Code §43.31997 Cal ALS 59; 1997 Cal AB 157; Stats 1997 ch 59 Notwithstanding any other provision of law, a mother may breastfeed her child in any location, public or private, except the private home or residence of another, where the mother and child are authorized to be present.
