Signs & symptoms of a fever in babies
Unlike adults, babies can't tell you when they're feeling under the weather. So, it's important to watch for these common signs of a fever:- Flushed cheeks
- Warm or hot skin
- Irritability or fussiness
- Decreased appetite
- Lethargy or sleepiness
When are infants considered to have a fever?
The definition of a fever varies slightly by age:- Under 3 months: 38°C or higher
- 3-6 months: 38.3°C or higher
- Over 6 months: 38.9°C or higher
How to treat a fever in a baby at home?
If your little one has a mild fever, there are several safe and effective home remedies you can try:- Give them plenty of fluids: Breastmilk, formula, or water (for babies over 6 months) can help prevent dehydration.
- Dress them lightly: Overdressing can trap body heat and raise the fever. Stick to lightweight clothing and avoid bundling.
- Give them a lukewarm bath: This can help bring down a high fever gradually. Avoid cold baths, as they can cause shivering and raise the body temperature.
- Use over-the-counter medication: For babies over 6 months, you can give paracetamol or ibuprofen to reduce fever and discomfort. Always follow dosage instructions carefully.
- Keep them comfortable: Offer plenty of cuddles, read stories, or put on a soothing movie. A calm, relaxed environment can help your little one rest and recover.
- Monitor the fever: Check their temperature every few hours to ensure it doesn't rise too high or persist for too long.
What to avoid?
While home remedies can be helpful, there are a few things you'll want to steer clear of:- Alcohol baths or rubbing alcohol on the skin (can be absorbed through the skin and cause poisoning)
- Aspirin (can cause serious side effects in children under 16yo)
- Overdressing or bundling (can trap heat and raise the fever)
When to consult a doctor?
In most cases, a mild fever in a baby is nothing to worry about. However, there are certain situations where you should seek medical attention:- Fever >38°C in a baby under 3 months old (even if they have no symptoms)
- Fever over 40°C in any age
- Fever lasting more than 3 days
- Signs of dehydration (dry mouth, no tears, sunken soft spot on their head)
- Difficulty breathing or lethargy
- Rash or other concerning symptoms such as vomiting, headache, or neck stiffness.
- Trust your instincts – if something doesn't seem right, it's always better to be safe than sorry.

Instead, dress them lightly, keep the room cool and comfortable, and offer plenty of fluids when they wake up.

Fevers often seem worse at night due to our natural circadian rhythms. Our body temperatures tend to be slightly higher in the evening and overnight hours, which can cause a fever to spike during this time.In conclusion, managing a fever in a baby can be nerve-wracking, but with the right knowledge and approach, it's often a manageable condition. By monitoring your little one closely, trying safe home remedies, and knowing when to seek medical attention, you can help them feel better and recover quickly.
