The people most excited about Halloween are little kids. For humans aged between 2.5 and 10 years old, there’s really nothing better. They get to dress up and go out—at night!—and strangers give them candy. There are leaf piles to jump in and fake skeletons to scream at. But it can also be a nightmare, if they get too scared. Halloween works best for young kids when it's a mixture of spooky and sweet, one that's light on the spooky and heavy on the sweet.
