If a 1-week-old baby has a fever and does not take antipyretic medication, the following measures can be used: First, the child can be given physical cooling. If the temperature is not very high and does not exceed 38.5°C below the axilla and the child is in good spirits, the child can be given physical cooling, such as applying antipyretic patches or applying warm wet towels to wipe the neck and underarms. Secondly, if the fever exceeds 38.5℃ and the child’s mental state is not good, acetaminophen suppositories or ibuprofen suppositories should be administered rectally.
