First thing you need to do is to inform the child's law guardian about this situation. If there is no law guardian, then make sure you get one assigned to your case so that he/she can raise these issues on behalf of the child. If you are in IDV with a pending criminal matter and divorce, then you cannot go to family court to modify the existing order. Once you have a divorce matter pending in Supreme Court (IDV), then family court is divested of jurisdiction during the pendency of the action (unless the Supreme Court Judge refers the matter to family court - not common). Depending on the severity of the communication and its impact on the child's well-being, then 'supervised visitation' may be warranted until the behavior stops. Your request for a modification of the existing visitation arrangement should be commenced by way of Order to Show Cause before the judge presiding over your divorce case.
