Here are some links specifically on Biting at Daycare ~ I skimmed them and found lots of helpful info:

states in the article: "The child who bites needs to be closely watched by the parents or day care provider so the biting can be quickly interrupted. A parent’s response to biting should leave no question that they mean business. First, look the child straight in the eye and in a loud, sharp voice say "No biting. We never bite people" It is okay to startle the child who bites. This is not a time for child psychology and long discussions, such as "I know you are mad, but biting hurts and could cause an infection or scarring." Avoid giving the child something else to bite instead, such as a towel or a stuffed animal. The message should be clear: biting is bad. Lengthy conversations only gain biters the attention they sought. Then, the child should be immediately placed in "time out" for one minute per year of age. Make sure the youngster receives no eye contact or interaction while in timeout. Sympathizing with the victim is also helpful and may serve to avoid secondary gain for the biter" and goes on to say, "Remember, biting is an unacceptable behavior. It will quickly make any child and his or her parents very unpopular, and the act should therefore be removed from the youngster’s repertoire the moment it starts." (It is such a good article I bookmarked it in the event my little guy starts to bite.)
I hope some of this helps!
