Determining whether an infant with protein allergy will heal on its own depends on the situation. Firstly, if the infant’s protein allergy is very mild and the eczema is very mild, and there is no family history of protein allergy, and the symptoms of allergic enteritis are also mild, then most of the protein allergy symptoms can be cured. Secondly, if the infant’s protein allergy is very severe and has severe eczema, as well as very obvious allergic enteritis symptoms, and there is a family history of protein allergy, it is very difficult for the child’s protein allergy to heal itself, and interventions need to be actively given.
