Well, first of all, it should have a lovable protagonist. It could be a small puppy. Then there should be a relaxing environment, say a soft bed or a quiet meadow. The story needs to have a peaceful ending, such as the character falling asleep under the moonlight. In a 1 - minute bedtime story, you don't have much time, so these elements should be presented briefly but clearly. For example, 'There was a puppy. It was in its warm bed. The stars twinkled. The puppy closed its eyes and slept.' This shows all the necessary elements in a concise way.
A simple character, like a little mouse or a bird. And a setting, for example, a warm nest or a cozy cottage. Also, a calm event like going to sleep or getting ready for bed.
In a 1 - minute bedtime story, you need a relatable character. It can be a little fawn in the forest. The story also requires a simple situation, like the fawn finding a safe place to rest. A gentle mood is essential, perhaps created by soft wind or a motherly figure. For instance, the fawn was tired after a day of exploring. It came to a hidden glade. Its mother deer was there. The fawn lay down beside her, feeling safe, and soon fell asleep. These elements work together to make a short and soothing bedtime story.
