Accepted Answer

A 21-month-old child experiencing fever only at night can be concerning for parents. Here are some potential causes and what you can do:

Possible Causes of Nighttime Fever

1. Teething: Some children may experience slight fevers during teething, although this typically should not cause a high fever.

2. Infections: Viral infections (like colds or flu) can cause fevers that might be more noticeable at night due to natural body temperature fluctuations.

3. Ear Infections: Ear infections are common in young children and may cause fevers that worsen at night.

4. Respiratory Infections: Conditions such as bronchiolitis or pneumonia can cause intermittent fevers.

5. UTI (Urinary Tract Infection): Sometimes, UTIs can present with nighttime fevers and irritability.

6. Post-Vaccination: If your child received vaccinations recently, low-grade fever can be common as a response.

7. Environmental Factors: Overheating due to heavy bedding or clothing can cause a rise in temperature.

What to Do

1. Monitor Fever: Keep track of his temperature regularly. Use a digital thermometer for accurate readings.

2. Hydration: Ensure your child is drinking plenty of fluids. Fever can lead to dehydration, so offer water, diluted fruit juices, or oral rehydration solutions.

3. Comfort Measures:

Dress your child in light clothing to prevent overheating.

Use a fan or air conditioning to keep the room cool if necessary.

4. Medication: If the fever is uncomfortable, you can use age-appropriate doses of acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) to reduce fever. Always follow the dosing instructions based on your child’s weight.

5. Cool Compress: Applying a cool, damp cloth to the forehead can help bring down fever.

When to Consult a Pediatrician

Persistent Fever: If the fever lasts more than 24-48 hours.

High Fever: If the fever exceeds 100.4°F (38°C) consistently.

Additional Symptoms: If your child exhibits other concerning symptoms, such as:

Rash

Difficulty breathing

Severe irritability or lethargy

Vomiting or diarrhea

Signs of dehydration (dry mouth, no tears when crying, decreased urination)

Follow-Up

Keep a record of the fever pattern (time of occurrence, temperature readings, and any other symptoms). This information can help your pediatrician make a more accurate diagnosis.

If you are concerned or unsure about the symptoms your child is experiencing, it’s always best to consult with your pediatrician for personalized advice and evaluation.
