If you are giving notice for the DCG, then you must write in the termination letter your expectations. Such as, ANY DISRESPECT ON THE PART OF THE PARENT or breaking of your policies during the notice period will result in an IMMEDIATE TERMINATION with no refund of fees. I would also make sure you have someone there. If you have a husband, maybe make sure he is there, or a neighbor. I find bully parents have a harder time acting that way when there are witnesses.
