Fever in an 11-Month-Old Baby
A fever can cause extreme fussiness.

Your 11-month-old baby’s temperature will naturally elevate and decrease between the morning and night. However, a lingering elevated temperature can be a sign of an illness or problem, especially if it is accompanied by other worrisome symptoms. This makes it important to understand what can cause a fever in your 11-month-old baby and how you can treat it.

Definition and Signs

Your 11-month-old baby has a fever if his internal body temperature reads higher than 98.6 degrees Fahrenheit. A fever is your baby’s body’s natural way of fighting off some type of infection or illness. It can last anywhere from a few hours to more than three days. A fever can be accompanied by sweating, a pink or white rash, weakness, head pain, shivering, lack of appetite or dehydration.

Possible Causes

Your 11-month-old child can experience a fever if he is teething. In addition, he can develop a fever if he has been out in the heat too long. Viral infections such as influenza and roseola can also trigger a fever. In addition, some more serious infections, such as a urinary tract infection, meningitis or bacteria in the blood can cause a fever.

Treatment Options

With your pediatrician’s approval, give your child infant ibuprofen or acetaminophen to help control her temperature and any related pain. Remove her clothing or dress her in very light and loose-fitting clothes to help lower her fever. Sponge your baby down in a tub or sink of lukewarm water. Give her an oral rehydration drink for young children that contains both salt and water to help replenish any fluids lost due to the fever.

When to Call for Help

Contact a doctor or pediatrician immediately if your baby is inconsolable, crying nonstop, drooling excessively, has a stiff neck or rash, shows signs of having head pain, has problems swallowing, acts confused or develops pinpoint-sized purple spots on the skin that do not disappear when you press on them. These could be symptoms of a more serious infection or a condition such as purpura or petechiae in which blood vessels rupture beneath the skin.
