C.M.
Warm baths.....
Tylenol or Motrin for the fever....
Lots of liquids....
Take car rides if he has a hard time napping....
When my 18 month old is sick, I do just about anything I can to make him better..this includes letting him have his binky more often than just bedtime.
AND, sleep when he sleeps if he's still grouchy during the day. It'll help you get a breather too!
