we implemented an offical 'breast-feeding friendly' policy in my office last year. the primary point was that if someone was bothered by having to witness breastfeeding in one of our public spaces (say a reception area) we would provide a room to move that person to, so the mother could stay where she was and not be interrupted. if the mother preferred a private space we would provide that instead, but only if that is what she requested. otherwise it was the complainer that got moved.
the vast majority of staff responded by saying "weren't we already doing this? no big deal." not a single person thought this wasn't the right thing to do.
