Toddler with covid

No idea how she got it but our toddler (2 and a half) got covid. She is second day of symptoms and her test showed positive but faintly. She had a fever of 103 half an hour ago and I gave her more Advil. What can I do to help her through this? How did you help your kids at home? She can’t have much Advil/Tylenol because she is so young. Any remedies or tips? Please we need it. And also prayers as my baby might also be sick as well.
