This regimen will allow the mother to continue to breastfeed in almost all cases. Soy is another protein, which can cause allergic reactions, and in fact many babies who are allergic to milk have a cross-reaction to soy as well. For this reason, I rarely recommend the use of soy when babies have milk allergies. However, when hypoallergenic formulas are not available or affordable, a trial of soy formula may be recommended. Finally, parents should know that goat s milk has the same composition as cow's milk and is therefore not hypoallergenic.
Many parents confuse milk allergies with lactose intolerance.
It may be a problem from birth, or more typically it may develop later in life. Since it is not immunologically caused, lactose intolerance is not considered an allergic reaction. Soy formulas and milk formulas without the lactose will cause the symptoms to disappear. Many babies with milk allergies are referred to pediatric gastroenterologists when the symptoms are most severe. Diagnostic testing is often conducted to identify allergens and to evaluate anemia associated with bloody stool.
