If your infant is allergic to milk, talk to your pediatrician about which formula to use. Often, an extensively hydrolyzed elemental formula or a casein-hydrolysate formula is recommended for milk allergy in infants, as the proteins in these formulas have been extensively broken down. Alternatively, your infant’s doctor may recommend a soy-based formula, but soy allergy is as common as milk allergy. The prevalence of soy allergy is lower because of Western dietary habits.
