I am with Brit on this one, we were at Matilda and they were extremely helpful and encouraging to my wife. We've had numerous friends who delivered there, Adventist and Canossa who also had very positive experiences. In fact recently our friends who delivered in Queen Mary (their 2nd or 3rd kid) have mentioned how much the local attitudes to breastfeeding has been changing in recent years and how much more encouraging public hospitals are these days...
Having said that, my wife breast fed exclusively for 6 months, but her supply went away and we had to switch to formula at that time to supplement early solid foods. We've had our share of times over the past 18 months where all the supply (for a certain brand....only one our kid would drink actually) would disappear from nearly every Island store. Having said that I think it's more the issue with the distributor's incompetence and poor purchasing management by stores rather than mainlanders.
