My son had RSV and pneumonia at 1 yr old.
It took 2-3 weeks to get over it and I was on top of making sure he took his meds when he was suppose to.
It can be scary, but keep in touch with the Dr's office and note any changes in symptoms.
Temps do spike sometimes.
It's only when they won't go down again when they are a problem.
When doing nebulizer treatments, it often sounds like it's getting worse when it's getting better.
The medicine makes the mucus thin so it's easier to cough up.
It sounds awful but as long as the gunk comes up, he's getting better.
Try to keep the fluids up - it also helps keep the mucus thin.
Hang in there.
