As a Melbourne GP I echo both the need for support networks and the comment that breast feeding is not straightforward.
One book for breastfeeding that I think is very practical and offers realistic help for a number of scenarios is the Discontented Baby Book, written by a Queensland GP. I wish I had had it when I could not breast feed my first child. (But managed easily with my second- go figure).
(I have no connection with it by way of declaration- just read it and recommend it to patients)
