Written as if the author is speaking directly to the reader, this wonderful book draws the reader into the world of the butterfly. It does a very appropriate job of explaining the life cycle of the butterfly in terms a preschooler can understand. The illustrations are also quite nice. They complement the simple text very well. Especially nice are the ones near the end of the book of the little girl.
However, there are many nice books for preschoolers about butterflies. This particular book's special quality is in the way it invites the reader to imagine what it's like to be a butterfly. My preschoolers greatly enjoy "acting out" the book, starting as a caterpillar eating it's way out of an egg. The text is perfect for a simple preschooler "play". It gives them a creative way to move and physically explore what they've learned.
The ending to the book is very nice, too. Rather than just stopping once the caterpillar turns into a butterfly, or after explaining the common activities of butterflies, the book draws the reader back to reality. The reader doesn't look like a butterfly; the reader looks like, and is, a human child. The book briefly contrasts the differences between the butterfly and the human, listing good things about being a human.
The final pages list interesting facts about butterflies. Most are just a bit too complex for young preschoolers, but early grade school children should appreciate them. The admonition to not touch a butterfly's wings is well done and a nice way to end the book.
