What Temperature is Considered a Fever in Babies?
Before you can effectively manage your baby's fever, you need to understand what actually counts as a fever. According to the American Academy of Pediatrics, a rectal temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher is considered a fever in infants.
Normal body temperature in babies typically ranges from 97 to 100.3 degrees Fahrenheit. Temperature naturally fluctuates throughout the day, running slightly higher in the evening and after physical activity.
| Measurement Method | Normal Range | Fever Threshold |
|---|---|---|
| Rectal (most accurate) | 97.9-100.3 degrees F | 100.4 degrees F or higher |
| Armpit (axillary) | 96.6-99.0 degrees F | 99.0 degrees F or higher |
| Temporal (forehead) | 97.2-100.1 degrees F | 100.4 degrees F or higher |
How to Take Your Baby's Temperature Accurately
For babies under three months, rectal temperature provides the most accurate reading. The Mayo Clinic confirms that rectal temperatures provide the best readings for infants and toddlers.
To take a rectal temperature safely:
- Use a digital thermometer with a flexible tip
- Apply a small amount of petroleum jelly to the tip
- Place your baby on their back or belly across your lap
- Insert the thermometer gently, about half an inch to one inch
- Hold steady until the thermometer beeps
- Never leave your baby unattended during this process
Avoid checking temperature immediately after a bath or feeding, as this can give inaccurate readings.
Why Do Babies Get Fevers? Common Causes Parents Should Understand
Understanding why your baby has a fever can help ease your worry. Fever is simply your child's immune system responding to invaders. When the body detects bacteria or viruses, it raises its internal temperature to create an environment where pathogens struggle to survive.
Viral and Bacterial Infections
The vast majority of infant fevers stem from viral infections. Common culprits include colds, flu, and respiratory syncytial virus (RSV). These infections typically run their course in three to five days. Bacterial infections, while less common, may require antibiotics and closer monitoring.
Teething and Low-Grade Fever
Many parents wonder whether teething causes fever. Research from a prospective study found that while teething may cause mild temperature elevation, it does not cause true fever. If your baby's temperature exceeds 100.4 degrees F, the cause is likely illness rather than teething.
Post-Vaccination Fever
A low-grade fever within 24 to 48 hours after vaccination is completely normal. This indicates your baby's immune system is responding to the vaccine and building protection. Post-vaccination fevers are usually mild and resolve without intervention.
8 Natural Ways to Reduce Fever in Baby at Home
These natural fever remedies for babies work alongside your child's immune system rather than against it. Focus on comfort rather than eliminating fever entirely. Remember: always consult your pediatrician for babies under three months with any fever.
1. Keep Your Baby Well Hydrated
Fever increases fluid loss through sweating and rapid breathing. Hydration is one of the most important aspects of fever care. For breastfed babies, offer the breast more frequently. Breast milk provides both hydration and immune-boosting antibodies. Formula-fed babies should continue their regular feeding schedule.
For babies over six months eating solids, you can offer small sips of water or pediatric electrolyte solutions. Watch for signs of dehydration including fewer wet diapers, dry mouth, no tears when crying, and sunken fontanelle.
2. Give a Lukewarm Sponge Bath
A lukewarm sponge bath can provide temporary relief through evaporative cooling. According to Kaiser Permanente, the evaporation of water from the skin creates a cooling effect.
Use water between 85 to 90 degrees Fahrenheit. Gently sponge your baby's forehead, neck, armpits, and groin for five to ten minutes. Pat dry gently afterward.
3. Dress Your Baby in Light, Breathable Clothing
Overdressing is a common mistake when babies have fever. Heavy layers trap heat against the body, potentially raising temperature further. Dress your little one in a single layer of lightweight, breathable fabric.
The best fabrics for a feverish baby include cotton and bamboo, which are naturally temperature-regulating and moisture-wicking. Choose soft, breathable fabrics that allow your baby's skin to regulate temperature naturally. Bamboo fabric is an excellent choice as it keeps little ones comfortable without overheating. Explore bamboo baby clothes that are gentle on sensitive skin during fever recovery.
Signs your baby may be overdressed include sweating, flushed cheeks, and rapid breathing.
4. Maintain a Comfortable Room Temperature
Keep the room between 68 and 72 degrees Fahrenheit. Use a room thermometer to monitor conditions. Ensure light ventilation without direct drafts on your baby, and remove heavy bedding from the sleep area.
5. Apply a Cool (Not Cold) Compress
A soft cloth dampened with lukewarm or slightly cool water can provide soothing relief. Apply gently to your baby's forehead, wrists, or back of neck. Replace the cloth when it warms up. Continue for ten to fifteen minutes at a time. Never use ice or frozen items directly on your baby's delicate skin.
6. Encourage Rest and Skin-to-Skin Contact
Rest allows your baby's immune system to focus its energy on fighting infection. Follow your baby's sleep cues and understand they may need more sleep than usual. Skin-to-skin contact provides comfort and can help regulate temperature naturally. Keep the environment calm and quiet.
7. Use a Cool-Mist Humidifier
If fever accompanies cold or congestion symptoms, a cool-mist humidifier adds moisture to the air and eases breathing. Always use cool mist rather than warm mist, which can overheat the room. Clean your humidifier daily to prevent mold and bacteria growth, and position it safely away from your baby's reach.
8. Continue Breastfeeding for Immune Support
HealthyChildren.org confirms that breast milk provides babies with antibodies that help fight infection. What makes this even more remarkable is that your body produces specific antibodies when exposed to your baby's illness. This means your milk is customized to fight whatever your little one is battling.
Breastfeeding also provides hydration, nutrition, and irreplaceable comfort during illness. It is perfectly safe to continue nursing even if you are also feeling under the weather.
How to Reduce Baby Fever at Night Naturally
Nighttime fevers often spike higher due to circadian rhythm patterns, making those overnight hours particularly stressful for parents. Creating the right sleep environment helps your baby rest comfortably through the night.
Creating a Safe Sleep Environment During Fever
Maintain room temperature between 68 and 72 degrees Fahrenheit. Remove extra blankets and follow safe sleep guidelines. Use a breathable mattress and fitted sheet only.
For nighttime comfort, dress your baby in a single layer of soft, breathable sleepwear. A lightweight cotton or bamboo onesie allows heat to escape while keeping your little one comfortable. Browse breathable baby sleepwear that is perfect for fever nights, soft against sensitive skin and designed to prevent overheating.
Position your baby's sleep space within hearing distance so you can monitor them throughout the night.
Should You Wake a Sleeping Baby with Fever?
Generally, sleep is healing. Allow your baby to rest rather than waking them to check temperature. Exceptions include when baby has not urinated in six or more hours, shows signs of distress, or you notice concerning symptoms.
Trust your parental instincts. Check on your baby regularly, but prioritize their rest.
Age-Specific Fever Care: What Every Parent Needs to Know
Your baby's age significantly impacts how you should respond to fever. What is appropriate for a one-year-old may be dangerous for a newborn. Here is age-specific guidance.
Newborns (0-3 Months): When Fever Requires Immediate Medical Attention
The American Academy of Pediatrics emphasizes that newborns cannot fight infections as effectively as older babies, making immediate medical evaluation critical for any fever in this age group. While most fevers do not lead to serious illness, the risk of serious bacterial infection is higher in young infants. While awaiting medical care, keep your baby comfortable and continue feeding.
Infants 3-6 Months: Safe Natural Care Options
Call your doctor for temperatures of 101 degrees F or higher. For lower fevers, you can safely try natural comfort measures including lukewarm sponging, increased hydration, and light clothing. Monitor closely for additional symptoms and trust your instincts.
Babies 6-12 Months: Expanded Comfort Measures
More natural options become available at this stage. You can offer water and appropriate foods if your baby is eating solids. Watch for the 103 degrees F threshold for a doctor call. All comfort measures described above are appropriate for this age group.
Toddlers 12+ Months: Additional Natural Approaches
After the first birthday, honey becomes a safe option for soothing and hydration. Warm honey-lemon water can provide comfort. More food options are available, and all previous comfort measures remain appropriate.
What NOT to Do When Your Baby Has a Fever
Some traditional remedies are not just ineffective but actually dangerous. Knowing what to avoid is as important as knowing what to do.
Never Use Cold Baths or Ice
Cold water causes shivering, which raises internal body temperature. It can also cause shock in young babies. Always use lukewarm water only.
Avoid Alcohol Rubs
This outdated practice is dangerous. Alcohol can be absorbed through your baby's skin and cause alcohol poisoning. It can also be inhaled and cause respiratory problems. Never apply rubbing alcohol to your baby's skin.
Do Not Over-Bundle Your Baby
Extra layers trap heat against the body, potentially raising temperature. A single layer of breathable clothing is sufficient. Watch for sweating as a sign of overheating.
Never Give Aspirin
Aspirin in children is associated with Reye syndrome, a rare but potentially fatal condition. The American Academy of Pediatrics warns against giving aspirin to any child under 19 years old with fever-causing illness. If medication is needed, consult your pediatrician about appropriate alternatives.
Do Not Give Honey to Babies Under 12 Months
Honey can contain Clostridium botulinum spores that cause infant botulism. Babies under one year lack the digestive maturity to handle these spores safely. Wait until after the first birthday to offer honey.
When to Call the Doctor: Warning Signs That Require Medical Care
Natural remedies are appropriate for mild fevers in healthy babies, but certain situations require professional evaluation. Always trust your parental instincts.
