In the July 1997 American Baby magazine, in the Visit with a Pediatrician
column, by Alvin Eden, MD, there is an article on the nutrients your baby needs.
He states that breast milk does not, however, contain vitamin D, which is
manufactured by the skin when it is exposed to sunlight (wearing sunscreen does
not affect vitamin-D production).  Babies in this country, especially those who
live in cold climates, are rarely outside long enough to produce enough Vitamin
D.  And because sunscreen isn't recommended for babies under the age of six
months, and because you shouldn't expose your newbor to the sun for any length
of time anyway, so therefore if you breastfeed give her a supplement of vitamin
D starting shortly after birth (preferably at 2 weeks), and continue for as long
as you nurse.

On iron: Breastmilk does have iron in it but usually in low amounts that are not
enough to replenish baby's reserve.  Therefore, every breastfed infant should be
given supplemental iron starting at four months of age. This can be given via
iron drops or an iron-fortified formula.  Infants who are fed an iron fortified
formula-whether exclusively or in addition tro breast milk, do not require
supplemental iron.

Thought you'd like to know in case you begin to get calls about this.
