If the baby’s skin is broken if the ruptured skin is dirty, it is recommended that the wound be cleaned with water first, cleaned and treated with hydrogen peroxide for debridement, then disinfected with iodophor, applied locally with mupirocin ointment, and then bandaged with Band-Aids or gauze. If the skin rupture is large and there is obvious redness and swelling, it is recommended to take oral anti-infective drugs for preventive anti-infective treatment, such as cefixime granules and amoxicillin clavulanic potassium granules. Babies walk unsteadily during infancy and lack awareness of precautions, so they are prone to falls. After summer, it is recommended that babies wear knee and elbow pads to protect the skin of the joints and avoid damage to the skin of the joints when they fall.
