<<what I found disturbing is the following categories of people that
he
 feels *do* need supplementation:  pregnant and lactating women, the elderly,
 and
 **children who are breast-fed**(sic)  About breastfed children Dr. Caballero
 states:  ".....should receive supplementation of vitamins A, C, and D, and
 there is a preparation called Trivisol that is the standard issue to these
 babies". >>

This is yet another case where the new AAP guidelines can come to our aid,
at least for the 1st 6 months.  Here's the text, with supporting
references:

In the first 6 months, water, juice, and other foods are generally
unnecessary for breastfed infants.105,106 Vitamin D and iron may need to be
given before 6 months of age in selected groups of infants (vitamin D for
infants whose mothers are vitamin D-deficient or those infants not exposed
to adequate sunlight; iron for those who have low iron stores or
anemia).107-109 Fluoride should not be administered to infants during the
first 6 months after birth, whether they are breast- or formula-fed.
