Milk is the most common food allergy in infants, affecting between 2 and 6 percent of the infant population, states the University of Nebraska-Lincoln. Many people outgrow this allergy by the age of 6. A milk allergy occurs when there is an immune reaction to a specific protein, while a milk intolerance is usually due to one's inability to metabolize lactose, which is in milk. Symptoms of a milk allergy include problems in the gastrointestinal tract, the skin and the airways, and they usually occur within an hour of consuming a milk product.

Children often outgrow their egg allergies. Symptoms of an egg allergy include skin rashes, nasal congestion and vomiting, and they occur quickly after consuming eggs, explains Mayo Clinic. An allergy to eggs rarely results in anaphylaxis, but it is possible and can be life-threatening.
