Is 'Supplementing with Infant Formula to Prevent Cow's Milk Allergy' Necessary for Breastfed Babies? LLLI (La Leche League International) Statement Becomes an Information Sheet

NPO La Leche League Japan (Shijonawate City, Osaka Prefecture, Representative Director: Hitomi Iimura) has created a Japanese translation page of the statement released by La Leche League International (LLLI) on March 22, 2026, on the official LLL Japan website, making it also available for download as a PDF. It can be printed and utilized to share information regarding "supplementing with infant formula for the purpose of preventing cow's milk allergy" for babies who are breastfed. Regardless of whether there was infant formula supplementation early after birth, we hope that the mother's desire to "become able to feed exclusively with breast milk" is valued and that appropriate support can be obtained. We will continue to provide support that stays close to the feelings of each individual.
