All in all, breast is best. We all know that. You are never going to find me supporting something like this, though, because, in my opinion, having formula fed babies is a way lesser evil than not giving women the right to choose. Instead, we should be encouraging (not guilting) women to breastfeed and supporting those who choose to. It should be made as easy and accessible as possible.
But how far do we take the woman's right to choose and ignore a baby's right? Should we have the right to choose to not use a carseat, or sit baby on our laps while driving (as in some countries)? To discipline/punish our children *any* way we see fit? This is what I found interesting about the Indonesian legislation (which did include exemption in case of "medical problems") - that it focussed on the right of the child to breastmilk. A balance, perhaps, beginning with more information so that mothers at the very least can make a truly *informed* choice.
I *totally* agree that breastfeeding should be made as easy and accessible as possible - with skilled breastfeeding support available to *all* mothers and their families for as long as they need or want it. Also employers need to be truly and practically supportive of breastfeeding, not just pay lip-service to it - and if legislation is the way to go on this count, then so be it.
