Is this roseola?

[EarthMamaToBe]

12 month old boy

Sunday = fussy sleeps poorly

Monday = fever and clingy fussy nursed all day sleeps poorly

Tuesday = fever and clingy fussy nursed all day

Wednesday = no fever slightly fussier than usual

Thursday = no fever almost normal behavior a little cranky

Thursday evening = rash forms after bath on trunk

throughout he has wanted less solid food and more nursing but has not acted in pain.  Throat does not look red.  The rash does not seem to bother him at all. No runny nose either.  Mostly has acted normal the whole time.  Not in daycare but I do keep one 5 year old.

Kind of hard to tell from the pics, is the rash more like lace or is it spots?  I was thinking it looked kind of like Fifth's Disease.
