In the  journal Pediatrics, clinicians explain that so-called  
=B3hypernatremic
dehydration=B2 in newborns arises from the inadequate  transfer of breast milk
from mother to infant. Poor milk drainage from the  breasts leading to
persistently high sodium concentrations in milk may  worsen sodium levels in
the infant.



Here is my question and I am hoping maybe Dr. White can answer it.   When I 
attended a talk by Nancy last year she pointed out how colostrum has a  higher 
Sodium level than mature milk.  Also, it is well documented that  women's milk 
will increase the Sodium level when they are weaning.
So here is my question: if in nature the Sodium is higher than wouldn't it  
make sense that the baby's Sodium levels would be higher?  Also if the  
mother's milk supply is dropping and naturally the Sodium levels go up wouldn't  that 
mean the baby needs higher Sodium when the volume is low?
Are the laboratory Sodium levels based on formula feed babies?  Are  the 
laboratory Sodium levels the same no matter how old the baby is?
Somehow I don't think Mother Nature blew this one.
Awaiting answers.
