Infant Fever at 6 Months – As a parent, noticing your 6-month-old baby has a fever can be scary. Even a slight change in their body temperature may cause worry — and rightly so. But the good news is that most baby fevers are not dangerous. They are often signs that your baby’s immune system is working the way it should — to fight off an infection.
Understanding what causes infant fever at 6 months, how to treat it safely, and when to contact a doctor can help you feel more in control.
Infant Fever at 6 Months – What Is Considered a Fever in Babies?
The normal body temperature, for a baby is around 98.6°F (37°C). However, this can vary slightly throughout the day. In babies a lower bowel temperature of 100.4°F (38°C) or higher is considered a fever.
For a 6-month-old, using a digital rectal thermometer is one of the most accurate ways to check for fever. Ear, forehead, and underarm readings can be helpful too, but may not always be as precise.
Common Causes of Baby Fever
Fever isnt a disease itself – its a symptom, When your baby has a fever it usually means the body is fighting something. Here are common causes:
-
Viral Infections
- Colds, flu, roseola, and RSV are frequent causes of baby fever.
- These infections often resolve on their own and do not require antibiotics.

Bacterial Infections
- These include ear infections, urinary tract infections (UTIs), or pneumonia.
- Bacterial infections may require antibiotics prescribed by your pediatrician.
-
Post-Vaccination Reaction
- It’s common for babies to get a mild fever 24–48 hours after vaccinations.
- This is normal and usually resolves without treatment.
-
Overheating
- Dressing your baby in too many layers or staying in a hot environment can raise body temperature.
- Remove layers and cool the room to bring the temperature down.
-
Teething?
- While many parents believe teething causes fevers, it usually only leads to a slight rise in temperature — not a true fever.
Infant Fever at 6 Months – Signs and Symptoms Along with Fever

- Fussiness or irritability
- Warm or flushed skin
- Poor feeding or refusing milk
- Sleeping more or less than usual

Baby Fever Treatment at Home
For most mild fevers, home care is enough. Here’s how to safely care for a baby with fever:
1. Keep Your Baby Comfortable
Dress them in light clothing and keep the room temperature cool and calm. Avoid heavy blankets.
2. Offer Fluids Often
Hydration is very important. Breast milk or formula should be offered regularly, even if your baby drinks a little less than usual.
3. Use Fever-Reducing Medicine Only When Needed
Infant Fever at 6 Months – If your baby is uncomfortable or the fever is high (over 101°F), you can give infant acetaminophen (Tylenol).
But always consult your pediatrician first for correct dosage and safety.
4. Sponge Baths
A lukewarm sponge bath may help cool your baby gently. Never use cold water or ice packs.
5. Rest and Cuddles
Lots of sleep, love, and comfort will help your child recover quickly.
⚠️ Never give aspirin to a baby. This can cause a serious condition called Reye’s syndrome.
When to Call a Doctor
You should seek medical advice right away if:
- Your child is younger than 6 months old and has a fever of 100.4°F (38°C) or higher.
- The fever lasts more than 3 days
- Your baby is lethargic, hard to wake, or not responsive
- Signs of dehydration (fewer wet diapers, dry lips, no tears when crying)
- Has difficulty breathing
- Develops a rash, seizure, or persistent vomiting
- You just feel something isn’t right — parental instinct matters
Always trust your gut. If your baby “just doesn’t seem like themselves,” reach out to a pediatrician.
Preventing Baby Fever
While not all fevers can be prevented, you can reduce your baby’s risk of infections:
- Wash hands before feeding or touching your baby
- Avoid crowded places and sick contacts
- Clean pacifiers, bottles, and toys often
- Stay updated with vaccinations
- Avoid overheating – dress your baby in weather-appropriate clothing
Final Thoughts: Stay Calm, Stay Informed
