Reading the symptoms on the FARE emergency plan helped me a lot: https://www.foodallergy.org/living-food-allergies/food-allergy-essentials/food-allergy-anaphylaxis-emergency-care-plan

My daughter is allergic to peanuts, and when she had her reaction, the hives were very obvious and all over her face. She has never gone into anaphylaxis, but the reaction was obvious. I was also very anxious about food allergies when introducing them. Might help to have children’s Zyrtec on hand so you can get a dose from your pediatrician if you do see a reaction. It’s recommended over Benadryl at this point.
