What are some methods, besides tylenol, (acetaminophen) to cool down a child with a high fever?

Many: Encourage fluid intake, dress iightly or not at all, lukewarm bath (will feel cooler to child), cool moist compresses, air circulation (fans). Don't be so aggressive that the child gets goosebumps or shivers. If fever persists over 105 go to er. Otherwise the fever is only a problem if the child is uncomfortable; it is not necessary to try to bring the temp down to "normal".
