I don't think formula on prescription is going to work until the BF rates in Australia are higher and society is more BF friendly. Prescription only works very well in Pupua New Guinea (sorry for spelling) because there is support and information and the majority of women do BF(something like over 90%). If you make formula prescription only before the basics to ensuring BF has the best chance of working then there will be an increase of 1) mothers using poor substitutes like they used to and like they do in some 3rd world countries (condensed milk, powdered milk or just plain cows milk) 2) mothers going to the Dr while pregnant to get a prescription 'just in case'.
There is huge problems happening in the UK at the moment because the goverment and health professionals are pushing BF BF BF at all costs but there is little support and no education amongst health professionals on how best to help mothers. They have the best intentions but I hope the same thing doesn't happen in Australia. They need to educate Drs and nurses and midwives, and educate society because by doing that the mothers will be educated and supported and the BF rates will go up without the mothers and babies having to suffer.
