When your baby has a fever, it is usually a sign that their body is fighting an illness or infection. Fevers are generally harmless. In fact, they can be a good sign that your child's immune system is working, and the body is trying to heal itself.
The most important things you can do when your child has a fever:
It is a good sign if your child plays and interacts with you after receiving medicine for discomfort.
Call your child's doctor right away if your child has a fever and:
Looks very ill, is unusually drowsy, or is very fussy
Has been in a very hot place, such as an overheated car
Has other symptoms, such as a stiff neck, severe headache, severe sore throat, severe ear pain, breathing difficulty, an unexplained rash, or repeated vomiting or diarrhea
Has immune system problems, such as sickle cell disease or cancer, or is taking steroids or other medicines that could affect their immune system
Also call your child's doctor if:
Your child still "acts sick" once their fever is brought down.
Your child seems to be getting worse.
The fever persists for more than 24 hours in a child younger than 2 years.
The fever persists for more than 3 days (72 hours) in a child 2 years of age or older.
If you have any questions or concerns about your child's health, ask your child's doctor.
