Yes, in response to Tori Hocking's question--my daughter's reactions when
she injests milk protein:

She IMMEDIATELY responds with a "funny feeling" and a shiver.  So she has a
quick alert that something is wrong.  Within seconds her face begins to
swell, esp. lips.  Within minutes she develops hives over her face and
back.  Within a short time (5-10 min.) she has chest pains and difficulty
breathing.  Of course, we have an EpiPen (or used to!!) with us at all
times!  And are always prepared for a trip to the E.R.  Needless to say, we
are incredibly careful and read ingredients EVERY time we used a food
product at home or go to the grocery store or eat out.
