Yesterday my 18 month old DS woke up with a strange, red dotty (and sometimes pimply) rash all over his hands, feet, and knees. He was sick about a week ago so I took him to our doctor yesterday afternoon. DR ruled out baby measles, chicken pox, hand-foot-mouth disease, etc., and pretty much told me that he didn't know what it was, but that it should go away within a day. But, today the rash looks the same, if not worse on DS' feet- it doesn't seem to be itchy or bothering him, do any of you have any idea what it could be? Should I take him back to the DR. Any responses greatly appreciated! Kyla.
