Hi J.,
My son had roseola when he was 9 months old and I promise it will go away. Just keep loving her and keeping her comfortable. My son got a really swollen lymph node from roseola and it stayed swollen for a couple of months even though the other symptoms went away. As long as her fever doesn't reach 106/107 degrees she should be fine. Good luck!
P.S. I am a chiropractor so I have a little bit of experience.
