If your baby is allergic to wheat, you can continue to observe the symptoms if they are mild and temporarily avoid foods containing wheat. If the allergic symptoms are obvious, such as itchy rash, digestive symptoms, such as diarrhea, bloating, abdominal pain, or respiratory symptoms, such as coughing with shortness of breath, etc., the baby should receive symptomatic treatment and oral anti-allergy medication, such as cetirizine hydrochloride or loratadine. You should avoid wheat and wheat-based food ingredients such as bread, cakes, buns, dumplings, etc. for the next six months, and go to the hospital as soon as allergy symptoms appear.
