So sad. That must have been really humiliating for her.
I don't see any problem with breastfeeding in public as long as the mother is being reasonably discreet - which most do have the sense to be - to avoid potential embarrassment to others.
On the same subject, I heard on the radio a few nights back that they are thinking of outlawing breastfeeding in public again, I'm sure they only legalised it a couple of years ago, what's the sense in that?
