HELPPPP :( IS THIS FEVER NORMAL WHAT DO I DO

My 7 month old has his first fever and my heart is broken, he’s had a 101 fever for th past 3 days I’ve been giving him Tylenol every 6 hours and it goes down to 99 but then right back up again 7 hours later I took him to pediatrician and she suspects he has a ear infection as she saw a little bit of fluid in his left ear so I’ve been giving him medicine but with COVID out right now I’m extra worried has anyone gone through this and can give me advice on how long this lasts and what I can do to keep his fever down
