LO seems to get diaper rash pretty easily. Usually it clears up in a few days. But she's had a nasty rash for the past month or so that just isn't clearing up. We've been doing diaper free time, making sure she's really dry before diapering, and using Lotrimin and Desitin or Butt Paste. Does anyone have some magic recipe that I'm missing that will help clear it up??
