Barbara, I hope you will use the obvivous "visual aid" (at least it obvivous
to me- a nursing baby - the toddler might be a shock visual!) Rather than
the superiority of breast milk in comparing milks, maybe you should  focus
on the specificity of milk.  Rabbit milk for rabbits and cow's milk for
calves and so on.  We know that breast milk is superior to ABM and specific
to humans.  Superior seems to mean better ingredients to me. But the mix and
balance in each type of milk is specific to a species, not better (or
superior).  Hope this helps direct your other visuals/handouts etc.
Sincerely, Pat
