I used to try hiding DD2 when she was little, I was pretty uncoordinated then. but now she is such a sticky beak that if I try to cover her she pulls the cover off and gives me a silly look! But now if anyone looks at me I just stare back at them. I feed all the time at cafes and shopping centres when she needs to feed, no-one has said anything to me so far and I don't feel worried anymore.

I think some of that attitude is also knowing what I would say to someone if they did make a comment. So get your DW to think of things she would say if someone was to comment. There will be great suggestions on here, it is where I got most of my comebacks from
