Why Do I Have to Go to Bed? Book Review: Helping Children Understand the Importance of Sleep

For many families, bedtime comes with a familiar question:

“Why do I have to go to bed?”

Children are naturally curious, and when they’re not feeling tired yet, bedtime can feel confusing or even unfair. The Usborne book Why Do I Have to Go to Bed? gently answers that question in a way that children can actually understand.

Part of Usborne’s popular Questions and Answers series, this engaging lift-the-flap book helps children explore what sleep does for their bodies and why rest is such an important part of growing up.

Rather than simply telling children that bedtime is necessary, the book explains the why behind it, something many curious young minds really appreciate.

What Is Why Do I Have to Go to Bed? About?

Written by Katie Daynes and illustrated by Marta Álvarez Miguéns, this book follows the natural questions children often ask about sleep.

Through colourful illustrations and interactive flaps, it explains things like:

• why our bodies need sleep

• what happens when we’re asleep

• why bedtime routines help us rest

• why sleep helps us grow, learn, and feel better the next day

Each page answers a question in a reassuring and child-friendly way, turning bedtime from something that feels like a rule into something that actually makes sense.

Why This Book Helps Children Feel More Positive About Bedtime

Many bedtime struggles happen simply because children don’t understand why sleep matters.

When children feel like bedtime is something that’s done to them, resistance is natural. But when they understand what sleep does for their bodies and minds, the conversation can change.

This book helps children see sleep as something helpful rather than something frustrating.

The lift-the-flap format also makes the learning feel playful. Children can explore the pages at their own pace, discovering little explanations hidden beneath the flaps. That sense of discovery keeps them engaged while they absorb the message.

A Lovely Book for Curious Children Who Ask “Why?”

Some children find comfort in stories, while others want explanations. This book is especially helpful for children who love understanding how things work.
