Abstract: A method and kit for the sequential early introduction to an infant of at least nine allergens to decrease the infant's risk for developing allergies. The method and kit includes an initial lower exposure dose of a first allergen to be taken for a day or two, followed by a higher maintenance dose of the first allergen to be taken for a day or more. Additional allergens are added, each first at an initial lower dose for a day or more followed by a higher maintenance dose for a day or more. This patent continues until all nine allergens are being given to an infant at their maintenance doses. The allergens can be provided in powdered protein form in premeasured pouches for addition to baby formula/mother's milk. Alternatively, the allergens can be included in baby formula, or in other foods such as snack bars, cookies, or gels.
