My grandaughter has a fever of 100.9 and keeps going up and down should I take her to hospital?

Have you tried giving her tylenol or motrin? Does she have any other symptoms?

We have all day and it will go down then come back and she's only 6 months old

If she's only 6 months old and the fever reducer is not working, she needs to be seen. Please take her to the ER.

Get her checked out at the hospital. It may be something as simple as teething, but you need to take her in to find out what it is.

I tell my patients daily that a temperature above 100.4 should be checked out by a medical professional.

Since you have been giving medication, and this has not resolved, it is something that should be looked at to rule out infection.

As Teacherjenn4 said, it could be teething, but it could be something worse.

As a nurse I tend to try to treat at home, but my son, who is now 10, had viral meningitis at the age of 7 months. Best to rule everything out.
