I understand that it's up to the mum to do whatever she feels comfortable with. Personally, however, even though I was initially worried about breastfeeding in public in Hong Kong, I now don't even think about it. I do it whenever baby needs it, whether I'm on a bus, on the star ferry, in a restaurant, etc, just by hitching up my t-shirt. I've never had any comments, and if people look to see what I'm doing I just give them a big smile because I'm proud of myself. The more you do it in public, the more it will become second nature, so give it a go. I don't feel comfortable having to sit in a lonely, quiet bf room when out, so my choice is to do it wherever I like. Like I said though, it's up to the individual mum, but don't feel bullied into having to hide away if that's not what you want to do.
