Babies develop eczema due to localized dry skin, which results in itchy skin. The child may scratch the itchy area, possibly causing the eczema to break open. Once broken, it is prone to secondary bacterial infections. To address a secondary bacterial infection, first, disinfect the area locally, then apply an antibiotic ointment to the child, such as mupirocin or erythromycin ointment. After the lesion heals, actively maintain moisture in the skin. If necessary, under the guidance of a hospital doctor, use mild corticosteroid ointments. Generally, eczema can be well-controlled. Additionally, for children on formula, depending on the severity of the eczema, feed them amino acid-based formula or hydrolyzed protein formula. If the child is breastfed, the mother should be mindful of her diet and avoid consuming beef, lamb, nuts, seafood, and fermented rice wine. (Please consult a doctor before using any specific medications and do not self-medicate.)
