My kids recently fought over who would get this book in their personal bookcase. My boy is 5, my girl 3! Even little boys who like to watch action shows during the daytime and make guns out of tinkertoys will enjoy being put to sleep with this book...it is soothing and repetitive, and calmed both my children right down. They have nice bedtime memories, and I could probably read it every night as a ritual and they wouldn't mind. I am buying a copy for my sister-in-law's little baby who is due in May. My kids enjoy watching everything slowly going to sleep, and finally too, the reluctant little girl, who is limp in her mama's arms by the end of the book (as my own children were!). Highly recommended bedtime book, right up there with Goodnight Moon.
