C.O.
Fevers are typical for teething - high fevers anything over 104 is NOT normal.
The cold might be allergies....it's really bad this year...there is still a lot of pollen in the air so it might not be a cold - especially if the snot coming out of his nose is clear...if it's yellow or green, it's most likely a virus or cold....
When kids are teething there is a TON of saliva that creates mucous and such...is he has a fever over 103 or 104 - take him in - immediately...
