When your child has a fever, your thoughts begin to race: How high is too high? Should I give Tylenol? Or when do I call my pediatrician to be sure? 

Don't call the school office yet. Everyone's body temperature fluctuates throughout the day. The magic number for a fever is 38o and above, Cleveland Clinic reports.

You should not worry also in the following cases:

•If the fever lasts less than 5 days, your child's behavior is normal – playing, eating and drinking-wise, though he (she) might be a little tired.

•If your child recently got a shot.

When to call your pediatrician:

•You have an infant younger than 3 months.

•Your child's fever lasts more than 5 days.

•Your child is not acting as usual

Treatment tips

Keep your child cool, do not cover him (her) with heavy blankets.

Prevent dehydration by offering plenty of clear, but not red liquids.

Make certain your child rests.

For temperatures above 38 Tylenol can be given to children 3 months and older and ibuprophen can be given to children 6 months and older. Don't give your child aspirin, it can cause Reye's syndrome, a sometimes fatal disease.

Your children can return to daycare or school when they are symptom-free withour medication for 24 hours.
