NewsUSA) - Don't worry, Mom, diaper rash is very common and very treatable. It is estimated that more than half of babies between four and 15 months old develop diaper rash at least once. The causes of diaper rash vary from too much moisture or chafing to antibiotics, allergic reactions and yeast infections. Fortunately for new moms and expectant mothers, there's a world of advice on how to avoid rashes and how to treat them if they do occur. When little ones suffer from diaper rash, use the following suggestions to treat and prevent the irritation: * Change diapers often. Dirty diapers should always be removed immediately. If babies are in child care facilities or with babysitters, remind staff and caretakers to do the same. * Rinse with water as part of each diaper change. Your baby's bottom should be rinsed after every diaper change, using either a sink, tub, water bottle or moist washcloth. The skin should be gently but thoroughly cleaned. Avoid wipes with alcohol or fragrance. * Don't fasten diapers too tight. Not only can tight-fitting diapers chafe sensitive skin, they can also create a moist area vulnerable to diaper rash due to the lack of airflow. Before fastening diapers, pat the bottom dry as opposed to scrubbing -- scrubbing may further irritate the skin. * Use ointment regularly. Ointment acts as a barrier that prevents skin irritation, especially if your baby gets rashes frequently. Pediatricians, pharmacists and moms-in-the-know often recommend Dr. Smith's Diaper Rash Ointment, which contains the vital ingredient zinc oxide. Spread a generous amount onto the affected area during every diaper change. "The late Dr. Smith listened to mothers' concerns about creams and prescriptions that weren't working for their children, and he worked to make something more effective," said Neill Walsdorf, Jr. of Mission Pharmacal. "He produced something that we can all feel good about." If you're unsure about choosing an ointment, ask friends and other experienced moms. More than likely, you'll hear parents putting their trust in Dr. Smith's. It was developed by a pediatrician, and it has a very loyal following. You can find it at Walgreens and other drug stores and grocers. One last tip: Be careful when washing cloth diapers! Pre-soak dirty diapers, use hot water and mild detergents and skip fabric softeners and smelly dryer sheets. Double-rinse diapers if you're concerned about rashes.
