I am by no means an expert on allergies, it is so complex!  I feel this is from a 
good review study that talks about remission of gut symptoms and the rates 
of developing other sx as J. Tow has discussed:  

Ann Allergy Asthma Immunol. 2002 Dec;89(6 Suppl 1):33-7.

inpart>:  
The prognosis of CMPA is good with a remission rate of approximately 45 to 
50% at 1 year, 60 to 75% at 2 years, and 85 to 90% at 3 years. Associated 
adverse reactions to other foods develop in up to 50% and allergy against 
inhalants in 50 to 80% before puberty. CONCLUSIONS: CMPA is the most 
common food allergy in early childhood with an incidence of 2 to 3% in the first 
year of life. The overall prognosis of CMPA in infancy is good with a remission 
rate of approximately 85 to 90%. In particular, gastrointestinal symptoms show 
a good prognosis. An early increased immunoglobulin E-response to CMP is 
associated with an increased risk of persistent allergy to CMP, development of 
adverse reactions to other foods, and development of asthma and 
rhinoconjunctivitis later in childhood.

In regards to this discussion, something that is very concerning is the 
fortification of EBM for preemies with intact cow's milk proteins "human milk 
fortifier".  ugh.
