I purchased this book for my 2 year old granddaughter who is now 3. When I visit it is one of the books we read and talk about together. As the leaf falls, the animals react one after another. The facial expressions are funny and after the whole series of reactions work through with all the animals, the sequence begins again. It is a good book to introduce cause and effect to the very young child and also sequencing. Recently, my granddaughter started pre K and her teacher lost her copy of this book. So we purchased another and my granddaughter gave it to her teacher on the first day of pre K.
