Hi Jill, You are so lucky that the school is dairy free, my kids have
all gone to Jewish schools and all the food was/is heavily dairy, my
third milk and gluten free child is two now and it is the easiest its
ever been for us.( We have been gluten and dairy free for seven years
since my oldest was two and it does get easier .)  Everything that her
class eats is safe for her, we have baked gluten  and dairy free cookies
in their kosher kitchen (kosher stuff is available easily). We freeze
them and then they are ready for snacks.    I suggest that you do this,
it teaches the staff and the kids that it is easy and possible to eat
well with allergies. They give me recipes to convert to our flours and
try at home and then we do them there. Encourage them to feed the
children more fruits and vegetable, this costs more and is more work
than a box of .89 cent crackers but it can be done  Give them plenty of
written information, be there as often as possible, given other parents
and the school a list of foods that your child can eat, be very
specific, list fruits, vegs, air popped popcorn or a specific brand of
crackers or chips or whatever.  I find that people will respond to
specific suggestion, provide recipes etc.  I do this for the parents of
my olders kids' scout groups and it really helps them to provide safe
snacks.

Hope some of this info help, good luck,  Larissa Blechman
