I purchased this book because I was struggling with my baby's and toddler's night waking. I also had sleep problems. There is a slight stain on the top of the booklet, but the condition is otherwise clean. (Please check the photos.) I used this book for reference on sleep training, putting the baby to sleep, and getting a good night's sleep. ☆Book Details☆ A guidebook to help improve baby's sleep. - Title: Gentle Sleep Guide for Babies and Moms - Author: Etsuko Shimizu - Illustrator: Jun Kamiyama - Publisher: Kanki Publishing - Price: 1300 yen Thank you for looking.
