paisleyleaf - are you saying that formula somehow buys time? Not sure what your post means, sorry.
Diarrhoea can kill a young baby in hours or days.
You don't need infrastructure to support breastfeeding. It is there, in the women.
It needs no roads to transport it to the babies. It requires no pipelines or taps to produce water to mix and to clean bottles. It needs no fuel to boil the water. It needs no bottles or teats (which also need to be transported). It leaves no empty packets or cans which then have to be disposed of. It does not mean dependence on a consumer product which (when the aid runs out) has to be paid for.
To repeat - in other disaster situations, relactation is not the primary response to the need for the babies to be breastfed. It is one of a range of ways breastfeeding can be supported in the short and long term. I don't know enough about Haiti to predict what role relactation would play, but it is there, as a possibility, for some.
It is not hard to envisage situations where infant formula is needed, because none of these ways of getting a baby breastfed is available quickly enough. Of course these babies should get it, and as safely as possible. But on past performance, no one should be confident that distribution and decisions should be in the hands of manufacturers.
