If your baby’s legs are flooded, consider the possibility of intertriginous rash. Interscrub rash occurs in the groin and other parts of the body, due to the skin being impregnated with sweat or urine, and also because the baby’s legs are more obese, so it is easy to appear. The treatment of interscalene rash can be topical zinc oxide oil, pay attention to avoid skin friction, avoid local humidity, sweating, zinc oxide oil is usually used twice a day, 2-3 days to improve. If there is obvious exudation, you can apply boric acid solution wet first, and then give zinc oxide oil topically after the exudation is reduced. If combined with fungal infections, it is recommended to give a compound preparation for external use, such as trimethoprim cream once in the morning and once in the evening, a small amount of external application can effectively treat the rash without exudation. Pay attention to bathing your baby regularly to avoid impregnation by sweat or urine, which may lead to inter-rash. If the baby is fat, you can use gauze to pad up between the skin to avoid repeated rubbing and irritation.
