Diaper rash is a common skin irritation that affects infants, but what causes it? There are several factors that can contribute to the development of diaper rash such as prolonged exposure to wetness, chafing, sensitivity to diaper materials or detergents, and fungal or bacterial infections. Identifying the cause of diaper rash is crucial to effectively treating and preventing it. Proper diapering techniques, frequent diaper changes, and using gentle, fragrance-free products can help reduce the risk of diaper rash. If a rash persists or worsens, it's important to seek advice from your pediatrician. Understanding the causes of diaper rash can help parents take the necessary steps to keep their little one's skin healthy and comfortable.
