The order of adding complementary foods for allergic babies is the same as that for normal babies, from less to more, from fine to coarse, and from single to multiple. Since allergic babies may have allergic reactions, the addition of complementary foods should be strictly from single to multiple. When adding a new complementary food, usually first let the baby eat a spoon, whether there is a rash, vomiting, diarrhea, etc., if not, the next day may be appropriate to increase the amount of the same kind of complementary food need to be observed for about 5 days. If the baby to add complementary foods in the process of repeated rashes, diarrhea, etc., if necessary, need to improve the allergen test, in order to avoid allergic food. Repeated allergies can easily lead to poor digestion and absorption, thus affecting growth and development.
