The Good Sleep Guide is the book that made Sammy the UK's go-to voice on sleep. "As a long-time insomniac, I can never express enough gratitude to Sammy: this guide is a genuine life-changer. Read it and sleep!" — Nigella Lawson.
The Good Sleep Guide for Kids is the companion for parents: solving children's sleep problems from ages 3 to 10.
Both are available from all good booksellers.
Still to Come
The next two titles in the series.
