To make children's bedtime stories more interesting, you can interact with the child while reading. Ask them questions like 'What do you think the princess should do next?' in a story like 'Cinderella'. Also, you can use props. If it's a story about a pirate, you can bring out a small toy sword or a pirate hat. You can also create a cozy reading environment with soft pillows and a warm blanket so the child is more engaged in the story.
One way to make children's bedtime stories more interesting is to relate the story to the child's own life. If the story is about a brave hero, talk about how the child can be brave in their daily life. You can also change the ending of the story sometimes. Instead of the traditional ending of 'The Little Red Riding Hood', you can create a new ending where the little girl outsmarts the wolf in a different way. And don't forget to use lots of gestures while telling the story to make it more vivid.
