A good friend of mine, author of simpliful.com, shared this pediatrician-recommended potion: Combine equal parts Lotrimin, Auquaphor and Maalox and store in a small container. Dispense as needed. (Generic Lotrimin and Maalox may be easily substituted - my friend stores hers in a tiny Play-Doh container.)
Here's why it works: The Lotrimin is an anti-fungal cream and will treat any yeast that may be present. The Auquaphor is a very thick ointment that will coat the skin, adding a protective barrier. The Maalox helps to soothe the skin by cooling it on contact. Please try it. You'll be glad you did.
