I’m trying to find a children’s book, likely from the 1950s, about the size of and with illustrations similar to a Little Golden Book. It includes two complementary stories, each beginning at one of the covers. The first reads toward the middle of the book. Turned over, the book includes a second story that reads to the middle of the book. The stories are small morality tale, one of a boy or girl (I can’t remember which) who refuses to go to sleep and is allowed to discover how boring the house is when its quiet at night. The other story is of a girl (or boy?) who doesn’t want to get up in the morning and is allowed to sleep and find out what goes on while he/she sleeps through the day. In both cases, these tales are part of a strategy to get each child to wake up or to go to sleep. The illustrations are similar in style to those of Little Golden Books.
