Hi --

If you're confident that all sources of milk are gone from your 
daughter's diet, but she's still having stomach trouble (and yes, gut 
pain is not an uncommon reaction to milk protein), then it's time to 
look at alternatives.

First, make sure you're confident that milk is really gone.  My web 
site (listed in the signature line) offers some milk-free menus, along 
with well-vetted advice on how to keep the milk out.  I do suggest that 
you avoid processed foods while you're new at this, as they are a true 
minefield.  Also be sure to read the inactive ingredients on any 
required medicines.

If the milk is out and the aches continue, start a food diary.  Write 
down every little thing your daughter eats.  After 1-2 weeks, choose a 
food to eliminate in addition to milk.  Gluten and soy are good choices 
for a first go 'round.  Corn might make the secondary list.  Continue 
the diary while eliminating your choice of foods.  See if your daughter 
improves at all.  Also, insist upon a referral to a pediatric 
gastroenterologist.

Other than the pain, how is your daughter doing?  Is she growing at an 
appropriate pace?  Any rashes?  Any other issues at all?

I hope these suggestions help,
