The child has a problematic home-life but is otherwise very polite and happy, unfortunately they bite themselves, objects (erasers, clay and so on) and has bitten another student. I don't know how to deal with it. I have been trying to distract rather than punish but obviously now the child has moved on to other students I have to punish. I don't know what to do, i have thought about by a special needs chew necklace but we are not allowed to give anything that may seem like gifts to individual students. The parents are "Too Busy" to meet with me. How do I deal with this?
