There are two possibilities for the baby to be allergic to shrimp at this age: one is that the baby is too young to be allergic to protein in shrimp, and the child can still eat it after 3 years old, and there will be no allergic reaction. It is best not to eat hard-shell seafood within 3 years old; Two: it is a lifelong allergy of prawns. When I was a child, I may have severe allergies because of my low resistance. When I grow up, my allergies are slightly lighter and I will heal myself soon. Shrimp allergy is not necessarily allergic to other seafood. The baby adds the best small amount for the first time and observes it.
