I mean how hard is it to use your child as a shield? Or to have a blanket or burp cloth placed on top of your boob that you could easily slide down. No one is saying your priority shouldn't be your child. But you can focus on your child while limiting showing your full breast to the world. A little effort goes a long way.
But the concern should be to the child, not the other people in the room?
The concern should be for everyone. Of course you care about you child first. Say my child starts screaming in a restaurant. I don't cover their mouth and smother them to shut them up immediately. But, I don't completely disregard others by letting them scream while I change their diaper or rock them or figure out what's wrong. Ill remove myself if I can't calm them down quickly. It's courtesy and its now we live civilly in this world.
What has screaming got to do with this? Because I am unable to feed discretely (I would be really keen to know how you would feed a fidgetty baby discreetly with size G breasts and needing to use both hands to latch the baby btw, maybe you could tell us all as you have it nailed so well) I either have to let them scream which isn't civil as you say, or 'remove myself from the situation', so basically feed in private? Answer me this, if a woman isn't physically capeable of feeding her child without a little exposure that some women managed to avoid, should this said woman not feed at all in public to be civil????
The screaming baby was an example. I used it to illustrate how it would be if mothers had the same attitude they have towards BFing discretely toward everything. I mean I'm sure none of you let your baby scream in restaurants because you have regard for others so I just don't know why showing a full breast is any different.
To answer you question, I think that'a really hard for me to answer because I can't imagine a scenario where it being impossible to ever cover yourself at least enough to where people walking by couldn't see everything. If the baby is that fidgety than you could get them use to nursing with a cover. I have been BFing for 7 months and my son was quite fidgety and almost impossible to latch at first but I practiced being discrete while I was at home and personally I didn't nip til I was comfortable. I got him use to bottles of ebm early and inused those or I went to a handicap accessible bathroom or dressing room. There is a store in my town that has awesome dressing rooms and I went there lots of times in the beginning just to feed. I just think there are options maybe not the same as mine, but options.
