Formula milk from cow is considered an allergen which can trigger skin asthma that's why your pedia changed into hypoallergenic milk. Instad po na gumamit ng medication, iwas na lang si baby sa makpag trigger ng allergies. Usually skin asthma goes away in time. Pero for the time being much better na umiwas na lang sa mga allergens kesa gumamit ng gamot (usually steroids).
