HI -

Discovering lactose intolrance can be VERY different fromdiscovering a
real milk allergy.  Katherine Murrays web site (which is linked from
mine, by the way) includes LOTS of storeis from parents about how
they discovered their children's allergies.  The book by Dr. Doris
Rapp "IS This Your Child?" also inlcudes many anecdotes about how
people find out about a milk (or other food) allergy.

I'm afraid that my husband's allergy didn't develop until he
was an adult, so I can't lend any personal insight.

I hope this helps,
