A yeast infection is just a skin affliction that is normal. It is actually just a fungus and many over the counter medicines work amazingly well. Try using lotrimin powder every time you change your son. It will help stop the reoccuring yeast infections. I am a licensed preschool teacher and have changed many diapers as well as have 3 children of my own. This is what my doctor recommended when I asked the exact same question about my own son. I tried and was very satisfied with the results!
