Sleeping with Dad while teething

Because Jamin has had so many little problems he has often been fussy. I wondered if Jamin had an ear infection because he has been even more fussy. He might have an ear infection, but we found out that he is getting his first tooth! I am not excited about it as much because I am still nursing. If any of you have any good advice on how to teach babies not to bite while nursing I will forever be indebted to you (I am afraid of the whole biting thing!).
