Robert, I have been using formula instead of
milk for many years. It has all the vitamins &
minerals in it and you can dillute it how much
you want.  All you need is a little creativeness
and you do get used to the taste.  After going
through all the formulas over the years I find
that the taste has improved considerably and
they are creamier and less soy tasting than
years ago (36) to be exact, and you can get used to he taste.  Matter of
habit.
