There is limited research investigating maternal dietary practices and health care provider recommendations when providing breast milk (BM) to children with immunoglobulin (Ig) E-mediated food allergy.

To explore health care provider recommendations and maternal practices when providing BM to children with IgE-mediated food allergy and to assess for possible IgE-mediated reactions to BM while the mother consumed the food to which her child has allergy.

A web-based survey was distributed to breastfeeding (BF) mothers of children with IgE-mediated food allergies. Reported reactions to BM were scored by an allergist, provided only with the details of the possible reaction and not the suspect allergen or route of exposure, as to the likelihood that the reaction was IgE mediated.

A total of 133 mothers completed the survey. After food allergy diagnosis, 47.4% (n = 63) of the mothers reported that they were advised by their health care provider to continue BF without dietary restriction, 17.3% (n = 23) were advised to avoid eating the food(s) their child has allergy to while BF, and in 28.6% (n = 38), this concern was not addressed. A few of the mothers (12%, 16/133) reported that their child experienced an allergic reaction to BM. An allergist evaluated most of these reactions (75%, 12/16) as not likely IgE mediated.

This study exposed inconsistent recommendations for mothers providing BM to children with IgE-mediated food allergies. Most mothers were able to consume the food their child has allergy to without adverse sequelae. Standardized, evidence-based recommendations would enhance the well-being of these mother-infant dyads.
