Daniel seems to be on the mend.  The diarrhea is much better, and consequently, the rash seems to be much better.  He still has some disturbingly red patches, but most of his diaper area is normal skin color now.  The cotton training pants have helped immensely.  They are, of course, much messier than diapers, but if they help his skin, I don't mind cleaning up some messes.  We spread a shower curtain on the living room floor and put his toys on there so that he won't make a mess on the carpet, but he seems strangely determined to be everywhere but on the curtain.  Oh well - the carpet will be replaced in a few weeks, and for now, it's not too hard to clean up after him.  Thank you for keeping him in your prayers, and please keep it up!
