I have a fish (shellfish) and peanuts allergy. If I ate shrimp while pregnant, can my baby be born with the allergy? I know it sounds like a dumb question and I should know the answer, but I’ve read mixed reviews on it. I seen an article on Glow that said the baby won’t necessarily have the allergy just because the mom does. My reaction to shrimp and peanuts is very mild. Sometimes I can eat it and it can cause a small rash and sometimes it doesn’t. It’s weird. Have anyone had a mild peanut or shellfish allergy and still ate it and the baby wasn’t born with that allergy?
