Lisa,

I am in the middle of reading a very interesting book---Your Child's
Growing Mind by Jane M. Healy, PH.D.   She discusses the growth of the
brain throughout---how this relates to behavior, learning, etc.  Not once
is breastmilk mentioned for optimum brain growth, but I have learned to
overlook this.  :)  Any way, she states in her book, "...There is little
myelin present at birth, and it takes twenty or thirty years to finish
the process, moving from lower structures and those responsible for motor
programs (e.g., reaching, walking) to the highest centers for academic
skills, abstract thought, and wise decision making."    If it were me, I
would try the breastmilk.
