Fever is a common condition in children. For babies 3 months and younger who have a fever, they should see a doctor right away. Children 3 months of age and older with a low-grade fever can be treated at home with appropriate measures if no other symptoms are present. Newborns with a high or persistent fever should be evaluated by a doctor.

If your child wakes up in the middle of the night crying, and his skin is red, you need to take his or her temperature to determine if he has a fever. Although fevers themselves are not dangerous, sometimes they are a manifestation of other medical conditions. Young infants often have causes of fever that require treatment.

Infants under 3 months of age with fever require immediate medical attention to diagnose the underlying cause and treat if necessary. An infant is considered to have a fever if the baby's temperature is:
100.4°F (38°C) or higher rectally (rectal) 99°F (37.2°C) or higher than when taking the temperature elsewhere. For infants over 3 months, a low-grade fever does not always require medical attention.

Babies older than 3 months with a slightly elevated temperature usually don't need to see a doctor. You can treat a fever at home with the following methods:
3.1. Infant fever-reducing medicine Acetaminophen If your baby is over 3 months old, a safe amount of children's acetaminophen (Tylenol) can be given. Dosage is usually based on the child's weight. So your doctor may recommend weighing your baby if she hasn't been weighed recently or if she's been growing rapidly.
If your baby is not upset or fussy because of the fever, you may not need to give your baby fever-reducing medicine. In case the child has a high fever or is accompanied by unpleasant symptoms, fever-reducing medicine can be used to help the child feel more comfortable.
3.2. Adjust your baby's clothes
Dress your baby in light clothes and use only a light blanket to keep him comfortable and cool. Dressing babies too hot can interfere with the body's natural process of cooling down.
3.3. Lower the temperature Keep your baby's house and room cool. This can help prevent your baby from overheating.
3.4. Give your baby a warm bath Try using warm water to gently rub your baby's body. When touching with your inner arm, the water temperature should be warm, not hot. Take care during the bath to make sure your baby is safe.
Avoid using cold water, as this can make your baby shiver and increase body temperature. Dry your child immediately after bathing and dress him in light, comfortable clothing. Do not use alcohol-based body wash or wet wipes to wipe down your child's fever as this can be harmful.

3.5. Replenish fluids Dehydration is a possible complication of fever. Give your baby water, breast milk or formula regularly. Make sure your baby still has tears when crying, a wet mouth, and a wet diaper frequently.

An infant under 3 months of age has an elevated temperature An infant 3 - 6 months old has an rectal temperature of 102° F (38.9°C) or higher Baby 6-24 months old with a fever above 102°F (38.9°C) for more than 1 - 2 days with no other symptoms Baby has a fever that lasts more than 24 hours or occurrences Your baby is irritable (a lot fussy) or comatose (weaker or more sleepy than usual) Your baby's temperature doesn't drop for 1 hour or longer after your baby's dose of fever-reducing medicine has been given appropriate birth Child develops other symptoms, such as rash , poor feeding or vomiting Child is dehydrated (not producing tears, saliva or diapers drier than usual) In summary, how to treat fever in infants Birth will vary depending on the age of the child and the symptoms that accompany the fever.
