Saw this on TV. If your little one is scared of getting up in night because of monsters or other scary things, for a girl use a little talcum powder, pretend its fairy dust get her to blow it in the air tell her its removing the monsters then walk to front door with arms waving and get her to wave them out the door telling her you can see them going away. For a boy use a pirate theme and get them to use a sword to wave them out the front door. Good luck!
