No, I am not saying don’t say anything. Share your view and knowledge of the situation. Just sharing with you my knowledge of the system. And sometimes actions speak louder than words. Tell the story, but give them action. I don’t know that situation, but if you feel like you and your h are the best possible solution and the only thing holding cps from letting the kids go with you is your father. Then, I would explore ways for my father could stay somewhere else for a short time just until kids could potentially go home with mom.
