I do know that dead baby feeling. For me however baby was not dead, just silenced, sleeping so the rest of "us" couldn't hear, see, feel the pain. No I am not DID but as most people who have lived through severe life-threatening abuse, I compartmentalized pieces of me. Maybe baby isn't dead. Please try to see her and offer her kindness. For me it took real live babies to help me to that. Good luck old friend.
