it probably is teething, but like with your friend's baby, there's always a chance it might not be. see if you can feel any swelling or see any redness on the gums, maybe that will allay your fears. give your pediatrician's office a call and they may say it's okay to give him some baby motrin. usually that will lower the fever, reduce swelling, and help a lot. or they might just tell you to bring him in (mine always did, although i think that was a stock answer for them). if not and you're still worried, feel free to take him in, since that's what they're there for. i always wished i had one of those ear looker thingys and knew what to look for, for an ear infection - my son had several his first year and i never thought that's what it was since he never grabbed at his ears at all. it sure would have helped! good luck!
