My 3yr old daughter has 2 small patches, one her neck and one on her cheek (same side). neck is 1/4 in long, light pink in color, spotted with small blisters. face is 1/8 in long, light pink, spotted with blisters (same as neck). This appeared overnight, the blisters seem to be filled with a clear fluid, though none have burst.
Maybe unrelated, she has had a cough. It's wet, nonproductive with no wheezing. No prominent fever over the past few days.
