Any suggestions for a teething 7 month old? He already has two teeth. I don't see the ones that are bothering him coming in yet but he is chewing on everything with the right side of his mouth and pulling at his right ear. I've done teething rings and a cold wash cloth. Ive given him Tylenol because he has a slight fever but it doesn't seem to be helping the pain it just takes the fever away. He was just crying for an hour straight. He hardly ever cries, he's the happiest baby. So naturally i sat there and cried too feeling useless. I just want to take his pain away. I feel so bad and non of my normal remedies are working.
