I should add that when my 5 year old (she was 4 at the time) had Covid this summer, it knocked her on her ass with a high fever, but after 3 days she was essentially good as new. This RSV has been lingering since Sunday afternoon, and she is just now showing signs of coming out the other side. The fever isn't as bad, but the coughing, pink eye, and fatigue are hitting her hard.
