Owl, I think discretion is entirely possible with public feeding and should be expected to be honest, especially on non essential trips. Yes, we have a right to bf in public and that is great, but I do think we should be mindful of other people in public. Rights come with duties and do not mean you have carte blanche to behave as you wish regardless of others around you. Both my boys were extended bf, but there is no way I would find it acceptable to sit stripped to the waist in a public to tandem feed or give maximum skin to skin, when they were needing that. I just planned my trips around their needs for those few months.
It is the kind of attitude where you suggest that those who prefer discretion are either oppressed, prudish or whatever as others have said, that invite 'breastapo' comments and I kind of agree. Women who choose to be actively discrete when feeding have made a choice, respect, don't ridicule that. If we can't respect each others' choice, how can we expect the general public to do that?
I do think Claridges were ridiculous though, and a crying baby would have been much more intrusive.
