My 17 month old daughter Diana absolutely adores this book, as does her 31 year old mother! It has a remarkably calming effect on her when she's all wound up at the end of the day, and fighting sleep as children her age are wont to do. The wonderful rhythm of the words is soothing, and easy for her to understand. She has begun "reading" along with me, and it's delightful to actually witness her learning. Thank you, Sandra Boynton, for putting your remarkable talent towards such a wonderful thing as children's books!!!
