Moms of babies with peanut allergy

Out of curiosity, are you someone who eats peanuts? I’m an avid nut fun and eat peanuts and tree nuts all the time. You could say I have some type of nut on a daily basis. This was true during pregnancy and is true now while I’m breastfeeding. I introduced peanuts to my baby at 7 months and she had an allergic reaction. Vomiting and itchy hives all over her body. I’m wondering if my diet played a role in her allergy. Any insight based on personal experience?
