DEAR DOCTOR K: In a recent column you said that parents should give babies peanut products to help prevent peanut allergies. Does the new advice also apply to other common food allergens, like eggs or cow's milk?
DEAR READER: To answer your question I turned to my colleague Dr. Claire McCarthy, a primary care pediatrician at Boston Children's Hospital. For decades, the standard advice recommended by allergy specialists was to hold off on giving babies foods that commonly cause allergic reactions. Parents were advised not to give egg, dairy, seafood or wheat in their child's first year. And parents were told to wait until two or three years to give peanuts or other nut products. It turns out that was bad advice.
