Fever in babies should be evaluated by a physician; however, acetaminophen or ibuprofen can help to lower fever, and a sponge bath or lukewarm bath can help to reduce a baby's temperature, according to MedlinePlus. Giving an ice bath or using alcohol is not recommended and can actually make fever worse.
When a baby has a fever, it is important not to bundle the baby up in extra clothes or blankets, even if the baby has chills, since this can keep the fever from coming down or even make it go up. Instead, use a lightweight blanket on the baby and one lightweight layer of clothing. Keep the room not too hot or too cold; it should be comfortable. A fan can be used if the room is stuffy or hot, notes MedlinePlus.
It is important to not administer any medication to lower fever in a baby younger than three months unless a doctor clears it first. Always check the child's weight and follow dosing-by-weight instructions on the product's packaging. Acetaminophen can generally be given every 4 to 6 hours, while ibuprofen can be given every 6 to 8 hours. Ibuprofen is not recommended for babies younger than 6 months of age, and aspirin is never recommended for children unless a doctor prescribes it.
