The first step for a baby’s formula allergy is to eliminate the allergen, which means to stop using the formula that the baby is allergic to. If your baby is able to find breastmilk, breastfeeding is the first option, as there are very few babies who are allergic to breastmilk. If you can’t find breastmilk and have to drink formula, you need to take anti-allergy milk powder. Anti-allergic milk powder includes amino acid milk powder, deeply hydrolyzed protein milk powder and moderately hydrolyzed protein milk powder. Generally, babies with milk powder allergy need to choose amino acid milk powder or deeply hydrolyzed protein milk powder, and moderately hydrolyzed protein milk powder usually can’t solve the problem of baby’s milk powder allergy. We can choose NuKangTe, NuTe, AiYeShu, EnMinShu and JiaRuiBao anti-allergy milk powder, generally anti-allergy milk powder need to eat about 6 months, and then gradually stop.
