If your baby has a rash on the pubic area, consider diaper dermatitis, which is caused by poor local skin heat dissipation, infiltration due to sweat and other excrement retention, and skin inflammation caused by constant frictional stimulation between the skin during the baby’s daily activities. Therefore, in the treatment, you need to keep the local skin dry for a long time, while using breathable diapers or nappies, and change them regularly. Wash your baby’s skin immediately after a bowel movement, and use moisturizing lotions or skin creams for skin care treatment. However, if there are symptoms of skin breakdown and oozing infection, you need to go to a dermatologist for specialist treatment to avoid aggravating the infection.
