I would really recommend getting a FBA to find out what drives the biting behavior. They will observe for hours and then get objective data on what comes right before and right after the behavior. Then you will get a behavior plan out of that. A good behavior plan based of a well done FBA helps you know what to do (and not to do) in response to the behavior. More importantly, then you can over-teach the correct behavior to helps the child get what they want or need.
