Meow, I was referring to the original poster, who was considering what imagry her chid would ha growing up. As for mental health - DS will learn I don't lie to him about people breaking into our house and that will help him. We go hunting for gruffalos, but never has one come into our house! Santa breaks in through the chimney: could a thief? How does the Tooth Fairy do it - could anyone just come into my bedroom while I sleep? Some lies we tell because they are "magical" are just a source of fear for some children.
