The following measures can be used to deal with dermatitis in children: First, children should be given a controlled diet. Most children with dermatitis need to eat a light diet with less spicy and stimulating foods. If the child is allergic to dermatitis, such as allergies to fish, shrimp, eggs, or milk, the child’s diet should avoid such foods as much as possible. Secondly, you can moisturize your child in time. You can apply glycerin or infant moisturizing cream to the affected area to help moisturize the skin, and after the skin is moisturized, the child’s skin mucous membrane repair will be better. Finally, you can apply ointment to children. For example, if the dermatitis is caused by bacterial infection, you can apply erythromycin ointment or Bactrim to the child, and if it is caused by allergic dermatitis, you can apply mometasone furoate ointment to the child.
