Want to thank the people who responded about ADD and allergies.  The
response has been overwhelming.  It's great to know you folks are out
there.

To answer some questions :
We have read "Is this your child?", in fact, this was how we first made the
connection.  She's had some of the indications of allergies : ear
infections, skin rashes (mild), trouble toilet training - but never enough
to trigger a visit to the allergist.   (Requires a referral under our
plan.)

At this point, we're not really sure how to test her, as we go through
elimination/challenge: it's hard to know what to look for.  The milk
behaviors were fairly obvious, (tantrums for no reason, repetitive nonsense
words: these went away. As an additional bonus, she can now deal with kids
in groups, instead of needing one-on-one to have any interaction!) She's
not hyperactive at all: most of her issues revolve around not paying
attention or spacing out.  We're pretty used to her as she is, and unless
the challenge lasts quite a while it's hard to see how we'll notice a
change.  When focused (and not at school), you wouldn't know she had a
problem.  It's also possible she has both problems.  At least I would
rather be experimenting with foods that with drugs.  I get the
(non-scientific) impression that treating an allergy with Ritalin might
decrease the symptoms while the *cause* gets worse over time.

It's really heartening to hear from you all about your successes!  You've
got me fired up to go tackle the allergist and convince him this is real.
 I've talked to a couple of ADD experts, who were very excited at first,
but then the reaction was "well, if it's an allergy then it wouldn't
*really* be ADD then, would it?" ARRGGH!

Fourth grade has been a real tough school year (even with an excellent
teacher) and it's hard to convince people that my daughter's not lazy or
trying to ignore them.  The support in this group is wonderful.
