Hey zen
Tell them, they can only see their grandchild with supervised visits. I wouldn't let them see the child alone at all. You may find that they change their minds and that will demonstrate their true motives. Remember, they are only following orders by shunning you. If they could have an excuse to see you then it would help them to be able to see you too. Then, they can tell the cong, "we are only associating with you to save the grandchildren".
