I need your advice..

We took my 8 month old to the ER because she has been having fever for 3 days between 100.5-101.6 and yesterday we started noticing red bumps on her neck. The doctors told us that it’s a virus and that it will go away on itself. Today she woke up with the bumps on her forehead and on her stomach. They look really bad. I know the dr says no cream or medicine would help but have any of you gone through this with your baby and put some home made cream. Please help.
