Watching your baby come down with a fever can be distressing, but fevers are not inherently a bad thing. It’s actually one of the body's important defense mechanisms, and getting a fever means your baby’s immune system is responding to a germ appropriately.
What is a fever?
A fever is defined as a body temperature of 100.4°F (38°C) or higher. Under three months old, any fever over 100.4 is treated as a medical emergency. After three months old, fevers can be monitored at home under the guidance of your pediatrician.
Common causes of fevers
Most fevers are caused by mild viral infections that just need to run their course. Some fevers can be a sign of a more serious infection that needs antibiotics or medical attention.
Typical signs of a fever include:
Crying and fussiness
Excessive fatigue
Reduced appetite
Cold and flu-like symptoms
Feeling warm*Keep in mind that feeling warm to the touch doesn't necessarily indicate a fever, so it's essential to use a thermometer for an accurate measurement.
Taking your baby's temperature
It's recommended to use a mercury thermometer for accurate readings, as digital thermometers may not always be reliable. For babies under 18 months, a rectal thermometer is recommended. Apply a small amount of petroleum jelly or coconut oil to the thermometer's tip and gently insert it about half an inch into your baby's rectum. You can also use an ear or forehead thermometer.
How to support your baby at home
Doctors typically recommend treating fevers based on the child’s symptoms, not based on the fever’s number. So, if your baby is 100.4 but seems miserable, go ahead and consider medication such as infant acetaminophen. If your baby’s fever is 102 but they are alert, content, and playful, you may let the fever run its course. Keep in mind that Infant ibuprofen, such as Motrin, cannot be given until at least 6 months old.
When to worry about a fever past three months old
Fevers in newborns under three months must be treated as an emergency; This is to ensure that your newborn does not have a serious infection. However, if your baby is older, fevers can be managed proportionately like they would in children and adults –– as a normal, healthy immune system response warranting some extra TLC.
Offer your baby fluids to stay hydrated. Breast milk or formula is sufficient for babies, and older infants (6 months+) can also be given water.
Opt for lightweight clothing, maintain a comfortable room temperature, and avoid excessive use of blankets.
There are times when it’s also proportionate to get immediate medical help related to a fever beyond the newborn stage. Seek medical help if your baby or child is immunocompromised with underlying health conditions, or if you notice any of the conditions listed below.
