Diaper rash is a common concern for parents, causing discomfort and irritation to their little ones. Understanding the causes can help prevent and treat this pesky problem. The most frequent culprits of diaper rash include prolonged exposure to wetness, friction from diapers, and irritants like soaps or wipes. Yeast infections, allergic reactions to certain materials, and infrequent diaper changes can also trigger the rash. Additionally, starting solid foods, diarrhea, or antibiotics can disrupt the delicate balance of the baby's skin, leading to a rash. By identifying these common causes, parents can take necessary precautions such as frequent diaper changes, using gentle products, and keeping the diaper area clean and dry.
