My definition of 'short and cute' for bedtime means something that wraps up neatly under 30 minutes, leaves a warm feeling, and doesn't have cliffhangers that keep my brain churning. I actively avoid anything serialized for this slot. Classics like 'The Little Prince' are beautiful, but sometimes the allegories are a bit heavy for right before sleep. I lean more towards modern slice-of-life or gentle fantasy where the stakes are low but the charm is high.
One author I consistently go back to is T. Kingfisher for things like 'A Wizard's Guide to Defensive Baking'—it's a novel, but the chapters are almost self-contained little episodes about baking sentient gingerbread men and dealing with a rogue sourdough starter, which is absurdly comforting. For pure short stories, 'The Wayward Children' series by Seanan McGuire has prequel novellas like 'In Mercy, Rain' that are standalone and feel like a bittersweet hug.
Lately, I've been reading translated Chinese webnovel snippets on sites like Chrysanthemum Garden. Stories like 'After Transmigrating into a Short-Lived White Moonlight, Had a HE with the Villain' often have fluffy, domestic extra chapters that are just the protagonists cuddling or cooking, completely divorced from the main plot's angst. They're perfect, disposable little candies. I also keep a physical anthology, 'How to Fracture a Fairy Tale' by Jane Yolen, by my bed—the twists are clever but the language is so rhythmic it just lulls you.
