Sounds to me like a formula rep has been making the rounds with a
carefully placed phrase, "Did you know human milk doesn't contain XXX?"

I listen to my co-workers at the Texas Dept. of Health returning calls
to approve specialty formulas.  It's amazing.  We can tell which reps
are hitting which areas with which special formulas based on the number
of prescriptions the docs suddenly start writing.  Miraculously a bunch
of babies in one area are lactose intolerant, then another bunch of
babies in another area have reflux.  Arrrrrgh!
