What’s it about?
The story.
Arlo is a very tired lion, but he simply cannot sleep. No matter how hard he tries, his thoughts and wakefulness keep him from resting. Then Owl offers a calm, simple idea: think about somewhere peaceful, breathe slowly and let the body grow heavy. The story turns a recognisable bedtime problem into a soothing read-aloud ritual, giving children a practical sleep strategy inside a warm animal story. Catherine Rayner's illustrations are spacious, soft and expressive, making Arlo's tiredness and eventual calm easy for young readers to feel. The book is not a high-energy adventure; its strength is reassurance. It is especially helpful for families dealing with bedtime battles, anxious evenings or children who need gentle, repeatable cues for settling down. Adults are likely to appreciate that the message is useful without feeling clinical.

In the classroom
How it works in school.
A soothing bedtime read-aloud about a lion who can't sleep — gently reassuring for anxious children and a warm prompt for talk about worries.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.

Why they love it.
Why kids love it
The specific kick is the breathing technique — Arlo unable to settle anywhere, Owl quietly teaching him to think of somewhere peaceful, slow his breath, let his body grow heavy. A four-year-old who can't sleep gets the same instruction without anyone telling them to do it.

The Catherine Rayner most given as a baby-shower gift in the UK — gentle mindfulness ritual hidden inside a bedtime story, the breathing technique demonstrated rather than explained. The book to reach for during a bedtime-struggle phase.
