I am so sorry for your loss. Please in your spare time read Mark 5:38-42 for it read how Jesus brought back to life and health a young daughter and gave her back to the parents and verse 42 read: "The parents were beside themselves with great ecstasy". Jesus with the help of his father, will do this again soon, on an grander scale. So yes, you may see little Millie again, enjoying her again. Please find the needed strength and comfort from these facts in your very difficult days ahead.
