I concur with yelping and crating if it persists- they don't have to go in the crate long, a minute or two will suffice just so they know that a bite means playtime ends. Now, sometimes when you go to take them out, they will bite again just because they are frustrated- put them back in the crate right away. They are such social animals that they will catch on quickly.
