I found this site and I can't tell whose site it is, some of the refs
are old, but it gave a pretty good simple explanation of the
differences in various formula, and what population they might be used
for. Also there is a chart showing the protein and mineral
differences.

I have found this kind of info to be useful over the years, as it
seems that lactation consultants really do need to know something
about infant formula. Mainly to defend breastmilk and breastfeeding to
others who really don't understand the appropriate use of formula, and
that it should not be replacing breastmilk.

I've said this on lactnet before, but I have seen many times a
pediatrician who is trying to get a breastfeeding or partially bf
feeder/grower premie to gain weight, and the only strategy is to use a
22 calorie formula. An example would be a baby who eats about 20 mls
every 3 hours. If you add 2 cals/oz you will be adding about 11
cals/day to his diet. So, in my opinion, this is someone who is not
thinking this through, or really does not understand the use of these
formulas.

Please don't take this as a flame or in any way promoting the use of
formula. But if a baby is on formula, or is to be supplemented or
treated with formula in any way, there should be an understanding of
the various kinds and indications or contraindications.
