My Baby's Fever Comes & Goes

A fever that comes and goes in babies is alarming to parents. Often times, a fever is caused by a virus. However, if your baby's fever lasts longer than two days, call her doctor. You can also take a few steps to make your baby more comfortable during a fever, like providing plenty of fluids and dressing her in light clothing.

Causes

A fever that comes and goes in babies might be caused by a virus. Also, if your baby is active during a fever, his body temperature might get higher. That's why it's important for your baby to rest and have less active playtimes during illness. Other possible causes include a bacterial infection or an inflammatory condition. The best person to determine the cause of your baby's ongoing fever is his pediatrician. He will likely want to evaluate your child.

Fever Reducers

Talk with your doctor about using a fever reducer. For a low-grade fever, your doctor might recommend skipping it. Using a fever reducer with a low-grade fever might cause your baby's illness to last longer, reports MayoClinic.com. However, if your baby has a fever of 101 degrees Fahrenheit or higher, your doctor might recommend using a fever reducer, like acetaminophen. Never give your baby aspirin. This medication is linked to the potentially fatal condition Reye's syndrome.

Prescription Medications

If your baby's ongoing fever is caused by a bacterial infection, your doctor might prescribe an antibiotic. Administer the medication to your baby as recommended by her doctor. Don't ever discontinue antibiotic use early – even if your baby is feeling better. Doing this might prolong her illness.

Red Flags

There are times when your baby's fever is a reason for concern. Anytime a baby under 3 months of age runs a fever, you should contact his doctor, recommends MayoClinic.com. At this age, the immune system is young – and fevers should be monitored carefully. For older babies, contact the doctor for fevers of 101 degrees Fahrenheit or higher.

Also, if your baby seems uncomfortable when he urinates, contact his doctor. It's possible for baby's to run an ongoing fever with a urinary tract infection. Also seek medical care if your baby has unexplained irritability or seems lethargic or unresponsive.
