Hey hun hope she is okay.

Not sure about a measles rash but if you press down on it with both thumbs, kind of dragging your thumbs away from each other, does the rash disappear and then reappear when the skin bounces back? If it does, it is most likely a viral rash (which is something that often goes along with any viral infection like a cold and temperatures in children & babies).

I have rushed DD to hospital before with this as it spread so quickly and was everywhere. Hopefully both girls will be okay
