No matter how gruesome the diaper rash, just brown some all-purpose flour (in a skillet on medium heat, put half a cup or a handful of flour in the skillet and stir constantly until brown ... don't burn it). Sprinkle it on after ever change. After about two or three changes, even the most stubborn, painful diaper rash will be history. My mother told me about this when I called her in a panic because I had no money for expensive creams or salves that may not work. I use it faithfully now.
