As society becomes more industrialized, the incidence of allergic diseases is increasing. Eczema is the most common and earliest age-onset skin disease. Eczema can occur as early as half a month after birth, and children who are artificially fed are more likely to develop eczema earlier and more severely than those who are breastfed. What should I do if my milk-drinking baby has eczema? Should you switch to another brand of milk right away? Switch to goat’s milk? Or should I switch to soy milk or other supplements? Mothers are very eager to know the answer. However, there is no single answer. The same baby with eczema is fed with cow’s milk, but at different ages and with different causes of eczema, the advice from the doctor is different. All foods (including breast milk, eggs, noodles, etc.), inhalants (including pollen, mold, insects, odors, etc.), and contacts (sand, plastic, rubber, etc.) can cause allergies, so milk is not the only cause of eczema. When your baby gets eczema, you don’t have to change the milk right away. You should go to the hospital first to check if you have an allergy to milk or milk additives and choose an appropriate supplement under the guidance of your physician. If the examination reveals that the allergy is not caused by milk or its additives, it is recommended to continue to consume the original brand of milk; if it is an allergy to the added ingredients of that brand, choose another milk that does not contain that additive; if it is a milk allergy, depending on the age of the affected child and the proportion of food taken up by the supplement, you can choose amino acid milk powder, partially hydrolyzed milk powder, goat milk, soy milk or other supplements. If there are no conditions to go to the hospital, mothers can also determine whether they have a milk allergy initially by the following methods: after the appearance of eczema, first stop using the milk being consumed and choose amino acid milk powder to consume for a week to 2 weeks to observe the changes in eczema; then continue to consume the original brand of milk and continue to observe whether the eczema worsens or recurs; if the eczema subsides after stopping the original brand of milk and reoccurs after adding it, then it is certain that the original If the original brand of milk induces eczema, it is recommended to replace it. If the eczema does not change after replacing the amino acid formula, then it is not the cause of the milk. In conclusion, milk is a good milk substitute that we should not give up lightly. Moreover, as the body grows older, it gradually tolerates milk proteins, and most babies with milk allergies as children can grow up to consume milk and products again.
