Is my son sick, teething, or both?

We are going to the doctor this afternoon, but before we do I wondered if some parents here might be able to give me some insight.

My 26 month old son is refusing food. He’s still eating a little here and there, but usually he has a healthy appetite. No matter what I give him (even old favourites) he’s just not interested. Usually when he’s teething he’s pretty fussy about his food, so perhaps his canines are coming in. But he won’t let me look in his mouth or put a finger in to feel.

Other symptoms include a little cough, a little irritability, lots of salivating. This has been going on for two days.

Care to share your toddler teething experiences? Any thoughts on the matter would be appreciated.
