Dear Anne,
I don't remember all the details in your original reflux posting.
There are other causes of reflux besides dairy allergies.  Reflux is
especially common in very low tone (hypotonic) babies because the flap
closing the esophogus is floppy.  These babies may not spit up much
because the reflux goes up and then down quickly.  However, the sstomach
contents is very acidic and can burn their throats and vocal cords.
They develop a hoarse cry and later a hoarse voice.

In my area, reflux was an extremely common diagosis for a while a few
years back. Mothers were told to do all manner of weird things to solve
the problem.  In most cases, the degree of intervention was completely
unwarranted--the babies were just spitters.  However, the is a small
subset of the population for whom it is a real, long term [hysical
problem. I know one of these children well.  She is now 8 yo.
Ironically, she nursed OK, didn't spit up much (it came up and then
down) but ate very lightly--was always borderline FTT.  THe mother was
off dairy for other reasons. She has significant throat and vocal
problems now.  Should her mother done something different at the time
she was an infant?  It's had to know what would have worked in
retrospect.
Hope this helps.
