I bf DD for about 14 months, until about 8 months ago.  While I didn't nurse in public often, sometimes it was necessary.  In principle, I knew we had a right to bf and people who didn't like it could piss off.  In practice, despite being as discreet as possible, I always felt conspicuous and embarrassed.  I never heard any rude comments, just a few dirty looks here and there.  

Before I breastfed, I didn't pay attention to moms in this position.  Now, of course, I have a whole new awareness about breastfeeding moms in public.  When I see one, I wonder if I should show my solidarity.  Should I smile as I walk by?  Should I say something encouraging to her?  If so, what?  I think I would have liked this, as my tension was due to being worried that strangers were going to be hostile or judging me.  Maybe if someone had said, "good job, I know that's hard to do," I would have relaxed a bit.  But maybe others want to be left the hell alone to nurse in peace.  

So what do y'all think?  Should progressive moms show solidarity to public bf moms? How?
