There is no need for the mother's milk to be tested for sodium.  The
mother should breastfeed, because it is best for her and her baby.
What a bunch of pseudo scientific claptrap to suggest that if the
sodium in the milk is 40 meq/l, say, the mother should not breastfeed.
When are they going to measure?  Colostrum has higher sodium.  If she
is not producing because of the stress of waiting for a result, the
milk sodium could be artificially high.  Even if a true value of the
sodium were 40 meq/l, why on earth would a baby be better on
artificial feedings?  Lots of babies around the world were fed on
plain cow's milk with a sodium of 55 meq/l and still did fine (unless
they developed gastroenteritis).
