my 19 month old daughter had a very restless nights sleep a few days ago, followed by a cold (runny nose,a little coughing and sneezing, less of an appetite, uncomfortable and possible off balance at times, and then really itchy all over and lastly a red, rash with raised little bumps... her skin is slightly sensitive and she will get a bit of ecxezma once in a while, but this is extreme. what is it? she has no allergies that i know of.
