The Book

Sleepy Star.

A children's book as a bedtime aid for parents · Coming December 2026.

A science-based bedtime book for parents of children ages three to six. Co-authored with Dr. Derek Reed. Sleepy Star is built around the bedtime routine that the research supports, told in a way a four-year-old will ask to read again.

Parents read the book with their child as the bedtime routine. The book introduces the framework that holds the routine together when the inevitable hard nights show up.

Sleepy Star distributes the bedtime steps across the reading rather than running them back-to-back. That is one of several evidence-based strategies the book uses to build cooperation with the routine and help a child fall asleep on their own, in their own bed.

Character mock-up. Final illustration in progress by Gary Wilkinson.
Closed → Open · the reveal
The Sleepy Star book open to a full night-sky scene with the star sleeping in bed; the routine flap is closed and blends into the picture.
Closed. The night-sky picture is whole; the step is hidden.
The same spread with the pink flap folded out, revealing the bedtime step drawn inside: a tooth and toothbrush.
Open. Fold out the flap, and the dry-erase step appears.

Each bedtime step is embedded in a fold-out flap, so the routine unfolds one step at a time as you read. Mock-up; final illustration in progress.

A parent's hand writing the bedtime step in marker on the dry-erase flap: the words 'Brush your teeth' beside the sleeping star.
The flaps are dry-erase. A parent writes the words or draws the step, the child completes it, and a quick wipe resets it for the next night.
Scrolling stories

The research, told as you scroll.

Visual essays built from peer-reviewed sleep data. Each story walks through a single question — what the evidence says, what it does not, and what it should change about the conversation at home or in clinic.

Cross-cultural sleep · 17 countries

Where your child sleeps is a cultural question.

Two cross-cultural studies show how room sharing, bedtimes, and total sleep vary by culture rather than by developmental stage. Why a single recommendation cannot fit every family.

Four-country comparison

How much children sleep across four countries.

Year-by-year mean sleep duration with the typical range of variation for Switzerland, Germany, the United States, and China. Descriptive findings, not prescriptions.

Recommendations compared

Two expert panels, one conclusion.

The National Sleep Foundation and the American Academy of Sleep Medicine arrived at near-identical sleep duration ranges by different methods. Where they agree, where they diverge, and what it means for parents.
