How can i reduce a 3yr old kids fever?

Acetaminophen or: Ibuprofen can help bring down the fever. Don't use aspirin. Hope your little one feels better soon.

Depends on how high: If it's less than 101 or so, then you might not need to do anything. Fever is the body's way of trying to kill the infection and also maximizes oxygen deliver to tissues to help fight the infection. If it's high enough, the first step is tylenol, (acetaminophen) which is great at reducing fever. If that doesn't help then you can try a tepid bath.

Be patient: This is not a life threatening emergency unless there are other symptoms like lethargy. Watch http://www.Youtube.Com/watch?V=zkoevqtnkis for more info.
