There are many children's stories that are written to be short and easily understood by young readers or audiences; one such story, 'Goodnight Moon,' by Margaret Wise Brown, is considered a classic by many, and its themes relating to sleep and relaxation make it an appropriate bedtime story. The main character of the 'Goodnight Moon' story is a bunny who is getting ready to go to bed, and the book is also quite short, with simple sentences laid out on illustrated pages that allow for a quick read.
Other short bedtime stories that have cute illustrations and calming themes include 'Brown Bear, Brown Bear, What Do You See' by Bill Martin Jr. and Eric Carle, 'One Fish, Two Fish, Red Fish, Blue Fish' by Dr. Seuss, 'Guess How Much I Love You' by Sam McBratney, 'Pajama Time!' by Sandra Boynton and 'Llama, Llama, Red Pajama' by Anna Dewdney. The last two items in this list are specifically related to bedtime, featuring anthropomorphic animals preparing themselves for bed. These are all short stories that can be read quickly before bedtime and are suitable for very young children. Older children may enjoy longer bedtime stories such as 'Where the Wild Things Are,' a classic children's story that features friendly monsters that nonetheless may be scary for very young children.
