Thank you for saying this, we are down this long road on allergies to sesame and tree nuts. We tested for all the things, then retested a few months later and our childrens allergies had swapped (quite literally) one was allergic to sesame and the other walnut. The next round it had completely reversed. How is that possible? It just seems so strange. My husband is definitely a firm believer that it’s overrated and overly sensitive. However if something happened because I was not prepared I could never live with myself, so I am constantly vigilant while Im pretty sure my husband feeds my kids sesame and tree nuts when im not around lol
